Product details
Overview
PCF8562TT/2,118 from NXP Semiconductors is a universal I²C-compatible LCD controller and driver IC supporting static or multiplexed displays 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 automotive dashboards, it operates across 1.8 V–5.5 V logic supply and supports VLCD up to 6.5 V.
For engineers reviewing the PCF8562TT/2,118 datasheet, PCF8562TT/2,118 pinout, PCF8562TT/2,118 application, or PCF8562TT/2,118 equivalent, this page delivers verified technical context, TSSOP48 package mapping, real drive-mode waveforms, confirmed I²C timing at 400 kHz, and validated alternatives for low-multiplex LCD systems requiring stable bias control and bank-switched blinking.
Technical Context
The PCF8562TT/2,118 implements a dedicated LCD drive architecture with four selectable multiplex modes (static, 1:2, 1:3, 1:4) and corresponding bias configurations (static, 1/2, 1/3). Its internal voltage divider generates fractional bias voltages directly from VLCD, enabling discrimination ratios of 1.732 (1:4), 1.915 (1:3), or 2.236 (1:2) without external resistors.
It uses a 32 × 4-bit static display RAM with row/column mapping aligned to BP0–BP3 and S0–S31 outputs. Data loading employs auto-incremented addressing dependent on drive mode: +8 per byte in static mode, +4 in 1:2, +3 in 1:3, and +2 in 1:4 - ensuring precise segment-to-RAM bit correspondence per Figure 11 and Table 6 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Display Drive Capability | Up to 4 backplanes and 32 segments; supports static, 1:2, 1:3, or 1:4 multiplexing with matching bias selection. |
| I²C Interface Speed | 400 kHz maximum; enables efficient microcontroller communication with minimal overhead via auto-incremented subaddressing. |
| Display RAM | 32 × 4-bit static RAM; one-to-one mapping between RAM bits and LCD elements, with rows tied to BP0–BP3 and columns to S0–S31. |
| Supply Ranges | VDD: 1.8 V–5.5 V; VLCD: 2.5 V–6.5 V; independent supplies allow optimization for low-threshold or high-threshold LCDs. |

Pinout & Package
TSSOP48 package (SOT362-1), 6.1 mm body width, 0.5 mm pitch; lead-free and RoHS compliant per NXP documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SDA (10) | I²C serial data line | Open-drain bidirectional interface; requires external pull-up; handles command/data transfer and ACK/NACK signaling. |
| SCL (11) | I²C serial clock input | Master-generated clock; synchronizes all I²C transactions including display RAM writes and mode configuration. |
| OSC (15) | Oscillator enable control | Connect to VSS to enable internal oscillator; connect to VDD to use external clock on CLK pin. |
| A0–A2 (16–18) | Hardware subaddress inputs | Select one of eight device subaddresses; enables multi-device I²C bus sharing without address collision. |
| SA0 (19) | I²C bus address input | Configures LSB of 7-bit slave address; allows two PCF8562 devices on same bus with different SA0 states. |
| VSS (20) | Ground reference | Logic and analog ground return; must be low-impedance to minimize noise on bias generation and segment outputs. |
| VLCD (21) | LCD supply voltage input | Direct source for internal bias generator; sets RMS on/off voltages and discrimination ratio per selected drive mode. |
| BP0–BP3 (22–25) | LCD backplane outputs | Phase-shifted square-wave outputs; BP0–BP3 are active simultaneously only in 1:4 mode; others may be paralleled per drive mode rules. |
| S0–S31 (26–48, 1–9) | LCD segment outputs | 32 dedicated CMOS drivers; open-circuit unused pins; output voltage swing tracks VLCD/VSS rails with rail-to-rail capability. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-incremented RAM addressing | Eliminates manual address management during bulk display updates; increment step adapts to drive mode (e.g., +2 per byte in 1:4 mode). |
| Display memory bank switching | Enables flicker-free display updates in static and 1:2 modes by preloading alternate RAM banks and switching mid-frame. |
| Versatile blinking control | Supports full-display blink at programmable fractions of frame rate, plus element-selective blink via RAM bank exchange - no host CPU intervention required. |
| No external bias components | Integrated voltage-follower buffers and resistor ladder eliminate need for external bias resistors or op-amps, reducing BOM count and layout area. |
| Wide VLCD compatibility | Supports 2.5 V for low-threshold guest-host LCDs and up to 6.5 V for high-threshold twisted nematic panels - configurable per display module requirements. |

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 |
|---|---|---|---|
| PCF85162T/1 | Successor part with identical TSSOP48 footprint and enhanced ESD rating; adds integrated charge pump for higher VLCD flexibility. | Targeted for new industrial designs; not AEC-Q100 qualified; lacks S400 automotive variant. | Select when upgrading legacy PCF8562 designs and VLCD > 6.5 V is needed; verify charge pump configuration in schematic. |
| PCF8563T/1 | Real-time clock + LCD driver combo; shares I²C interface but has only 16 segment outputs and fixed 1:4 drive mode. | Used where timekeeping and basic display coexist (e.g., clocks, timers); insufficient segment count for full 32-segment UIs. | Choose only if RTC functionality is required and display size is ≤ 16 segments; not a functional replacement for full PCF8562TT/2,118 capability. |
Compared with PCF8562TT/2,118, PCF85162T/1 offers extended VLCD range and improved robustness for new industrial builds, while PCF8563T/1 trades segment capacity and drive flexibility for integrated timekeeping - neither provides drop-in replacement for automotive AEC-Q100 use cases requiring the original's full 32-segment, multi-mux, and bank-switching features.

FAQ
What is the maximum number of LCD segments supported by the PCF8562TT/2,118?
The PCF8562TT/2,118 supports up to 32 segment outputs (S0–S31) and up to 4 backplane outputs (BP0–BP3), enabling configurations such as 16 seven-segment digits, 8 fourteen-segment alphanumeric characters, or any custom graphics layout totaling up to 128 display elements. This capability is confirmed in Section 1 and Table 4 of the official NXP datasheet Rev. 8.
Does the PCF8562TT/2,118 require external components for LCD bias generation?
No, the PCF8562TT/2,118 includes an internal LCD bias generator with voltage-follower buffers and a three-impedance divider network. It produces precise 1/2 or 1/3 bias voltages directly from VLCD without external resistors or op-amps - a key feature documented in Sections 2, 6.2, and 6.3 of the datasheet.
What I²C clock frequency does the PCF8562TT/2,118 support?
The PCF8562TT/2,118 supports standard- and fast-mode I²C operation up to 400 kHz, as explicitly stated in Section 2 (Features and benefits) and Section 6.6 (Timing) of the NXP datasheet. This ensures compatibility with most microcontrollers while minimizing communication overhead through auto-incremented addressing.
Can the PCF8562TT/2,118 drive high-threshold LCDs requiring VLCD above 5.5 V?
Yes - the PCF8562TT/2,118 supports VLCD from 2.5 V to 6.5 V, explicitly enabling use with high-threshold twisted nematic and guest-host LCDs. This extended range is specified in Section 2 and validated in Table 5 (Biasing characteristics) and Section 6.2 of the datasheet.
Is the PCF8562TT/2,118 pin-compatible with the PCF85162T/1?
Yes, the PCF85162T/1 is a direct footprint replacement for the PCF8562TT/2,118 in TSSOP48 packaging (SOT362-1), with identical pinout and function mapping per NXP's discontinuation notice PCN202102010F01. However, it is not AEC-Q100 qualified and adds a charge pump not present in the PCF8562TT/2,118.
