Product details
Overview
PCF8562TT/2,518 from NXP Semiconductors is a universal I²C-compatible LCD controller and driver IC supporting static or multiplexed LCDs with up to 4 backplanes and 32 segments. It integrates internal LCD bias generation, auto-incremented display RAM addressing, and hardware subaddressing. Designed for industrial instrumentation and embedded HMI displays operating from −40 °C to +85 °C, it delivers low-power operation across 1.8 V–5.5 V logic supply and supports VLCD up to 6.5 V.
For engineers reviewing the PCF8562TT/2,518 datasheet, PCF8562TT/2,518 pinout, PCF8562TT/2,518 application, or PCF8562TT/2,518 equivalent, key selection considerations include its 400 kHz I²C interface, TSSOP48 package with verified 48-pin segment/backplane mapping, selectable 1:2/1:3/1:4 multiplex drive modes, 32 × 4-bit display RAM, and support for independent logic/LCD supplies - all critical for legacy LCD panel integration and long-lifecycle industrial designs.
Technical Context
The PCF8562TT/2,518 implements a dedicated LCD timing engine synchronized to either an internal oscillator (OSC tied to VSS) or external clock (CLK input with OSC tied to VDD), generating precise frame signals derived via fixed division of the clock frequency. Its display RAM architecture uses row/column mapping aligned to backplane outputs (BP0–BP3) and segment outputs (S0–S31), with data pointer auto-increment values dependent on selected multiplex mode: +8 for static, +4 for 1:2, +3 for 1:3, and +2 for 1:4.
Hardware subaddressing via A0–A2 pins enables multi-device I²C bus configuration without address collision, while bank switching in static and 1:2 modes allows dual-display RAM banks for flicker-free updates. Blink control operates at programmable fractions of the clock frequency and supports full-display or selective element blinking via RAM bank exchange - no host CPU intervention required during active blink cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| I²C Interface Speed | 400 kHz - Enables fast display data loading without requiring high-speed MCU peripherals or additional protocol translation. |
| Display RAM Size | 32 × 4-bit - Stores up to 128 distinct LCD elements (e.g., 16×7-segment digits or 8×14-segment alphanumerics) with direct bit-to-element mapping. |
| Backplane Outputs | 4 (BP0–BP3) - Supports static, 1:2, 1:3, or 1:4 multiplex configurations; unused outputs may be left open-circuit or paralleled for enhanced drive strength. |
| Segment Outputs | 32 (S0–S31) - Drives any combination of numeric, alphanumeric, or custom graphics segments; unused outputs must remain unconnected. |
| Supply Voltage Range | 1.8 V–5.5 V (VDD); VLCD up to 6.5 V - Allows flexible power domain separation: low-voltage MCU logic and high-threshold guest-host or twisted nematic LCD panels. |
| Bias Configuration | Static, 1/2, or 1/3 - Matches electro-optical requirements of diverse LCD modules; discrimination ratios (e.g., 1.732 for 1:4/1/3) directly impact contrast performance. |

Pinout & Package
TSSOP48 package (SOT362-1), 6.1 mm body width, lead pitch 0.5 mm - compatible with standard surface-mount assembly processes and IPC-7351B footprint guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SDA (10) | I²C serial data line | Open-drain bidirectional interface; requires external pull-up to VDD for proper I²C signaling and multi-master arbitration. |
| SCL (11) | I²C serial clock input | Master-generated clock synchronizing all data transfers; rising edge samples SDA, falling edge drives SDA. |
| SYNC (12) | Cascade synchronization | Enables daisy-chaining multiple PCF8562 devices for larger displays; output of one drives SYNC input of next. |
| CLK (13) | External clock input | Accepts TTL/CMOS clock signal when OSC = VDD; determines LCD frame rate via fixed divisor (e.g., fframe = fclk/128). |
| VDD (14) | Logic supply | Primary power for internal logic, I²C interface, and control circuitry; must be stable within 1.8–5.5 V range. |
| OSC (15) | Oscillator enable | Connect to VSS to activate internal RC oscillator (~128 kHz typical); connect to VDD to disable and use external CLK. |
| A0–A2 (16–18) | Subaddress inputs | Set 3-bit hardware subaddress for I²C device selection; enables up to 8 PCF8562 devices on same bus without address conflict. |
| SA0 (19) | I²C address bit | Configures LSB of 7-bit I²C slave address (0x70–0x77); combined with A0–A2 for full 8-device addressing. |
| VSS (20) | Ground reference | Common return path for logic, oscillator, and bias generator circuits; must be low-impedance and decoupled near VDD/VLCD pins. |
| VLCD (21) | LCD supply voltage | Provides bias voltage to LCD panel; adjustable from 2.5 V (low-threshold) to 6.5 V (high-threshold TN/guest-host). |
| BP0–BP3 (22–25) | LCD backplane outputs | Drive complementary waveforms to LCD backplanes; output states determined by selected multiplex mode and RAM content. |
| S0–S31 (26–48, 1–9) | LCD segment outputs | Drive segment electrodes; each output toggles between VLCD and VSS based on backplane state and RAM bit value (1 = on). |
Key Features
| Feature | Design Value |
|---|---|
| Auto-incremented RAM addressing | Eliminates manual address management during bulk display updates - host writes sequential bytes and hardware advances pointer per multiplex mode rules. |
| Hardware subaddressing (A0–A2) | Enables up to eight identical PCF8562TT/2,518 devices on one I²C bus without software address remapping or external logic. |
| Independent VDD and VLCD supplies | Allows simultaneous use of low-voltage microcontrollers (e.g., 1.8 V ARM Cortex-M0+) and high-voltage LCD panels (e.g., 5.5 V guest-host). |
| RAM bank switching (static/1:2 modes) | Supports double-buffered display updates: assemble new frame in alternate bank, then atomically switch - zero visible tearing or partial refresh artifacts. |
| Versatile blinking control | Full-display or selective-element blink achieved via RAM bank exchange at programmable rates (e.g., 0.5 Hz, 1 Hz, 2 Hz), requiring no ongoing host CPU involvement. |
| No external components required | Internal voltage divider and buffers generate all LCD bias voltages; eliminates discrete resistors, capacitors, or op-amps in the bias network. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LCD controller and driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCF8563T/2,518 | Real-time clock + LCD driver hybrid; lacks 32-segment flexibility and 1:4 multiplex support; only 16 segment outputs. | Best suited for time-of-day display with minimal additional segments (e.g., calendar icons), not full alphanumeric or graphic panels. | Select only if RTC functionality is mandatory and segment count ≤16; not a functional replacement for PCF8562TT/2,518's full 32-segment capability. |
| PCF8576CT/1,118 | Higher segment count (48), supports 1:6 multiplex; requires external bias resistor network; no internal voltage-follower buffers. | Targets larger displays (e.g., 6-digit meters with icons) but increases BOM cost and layout complexity due to external bias components. | Choose when >32 segments or >4 backplanes are needed; avoid if design prioritizes component count reduction and internal bias simplicity. |
Compared with PCF8562TT/2,518, PCF8563T/2,518 trades segment capacity and multiplex flexibility for integrated RTC, while PCF8576CT/1,118 expands scale at the cost of external bias components and higher pin count - making PCF8562TT/2,518 optimal for balanced 32-segment, 4-backplane industrial HMI where simplicity and proven reliability are paramount.

How many unique LCD elements can the PCF8562TT/2,518 drive, and how is this determined?
The PCF8562TT/2,518 can drive up to 128 unique LCD elements, calculated as 4 backplanes × 32 segments. This capacity is realized in 1:4 multiplex mode (4 BP × 32 S = 128). In static mode, it drives 32 elements (1 BP × 32 S); in 1:2 mode, 64 elements (2 BP × 32 S); and in 1:3 mode, 96 elements (3 BP × 32 S). The actual usable count depends on the selected multiplex configuration and physical LCD layout in the PCF8562TT/2,518 implementation.
Can the PCF8562TT/2,518 drive high-voltage LCD panels, and what is the maximum supported VLCD?
Yes, the PCF8562TT/2,518 supports high-voltage LCD panels with a maximum VLCD of 6.5 V - sufficient for guest-host and high-threshold twisted nematic displays. Its internal LCD bias generator produces fractional voltages (e.g., 1/2 or 1/3 VLCD) without external components, and the wide VLCD range (2.5 V to 6.5 V) ensures compatibility with diverse LCD module specifications in the PCF8562TT/2,518 application.
Is the PCF8562TT/2,518 pin-compatible with other members of the PCF856x family?
Yes, the PCF8562TT/2,518 shares identical TSSOP48 pinout and electrical characteristics with other PCF856x variants (e.g., PCF8562TT/S400/2), including matching pin functions for SDA, SCL, BP0–BP3, S0–S31, and control inputs. This allows direct substitution within the same PCB layout when migrating between industrial and automotive-qualified versions - provided the specific ordering part number (e.g., PCF8562TT/2,518) is used per NXP's documented replacement guidance.
