Product details
Overview
PCF8562TT/S400/2,1 from NXP Semiconductors is a universal LCD controller and driver IC for low-multiplex-rate displays, supporting up to 4 backplanes and 32 segments. It implements static, 1:2, 1:3, or 1:4 multiplex drive modes with selectable 1/2 or 1/3 bias, features 32 × 4-bit display RAM, auto-incremented I²C addressing, and operates from 1.8 V to 5.5 V logic supply with independent VLCD up to 6.5 V - used in automotive instrument clusters and industrial panel meters.
For engineers reviewing the PCF8562TT/S400/2,1 datasheet, PCF8562TT/S400/2,1 pinout, PCF8562TT/S400/2,1 application, or PCF8562TT/S400/2,1 equivalent, key selection considerations include its AEC-Q100 qualification, TSSOP48 package compatibility, 400 kHz I²C interface timing, static-to-1:4 multiplex flexibility, and internal LCD bias generation eliminating external resistors.
Technical Context
The PCF8562TT/S400/2,1 integrates an I²C-bus controller, display RAM with hardware subaddressing (A0–A2), and a programmable LCD voltage selector that coordinates backplane/segment timing per selected drive mode. Its internal oscillator (enabled via OSC–VSS) or external clock (via CLK) generates frame timing derived by fixed division of input frequency.
It employs dual bank switching in static and 1:2 modes for flicker-free display updates, supports independent logic (VDD/VSS) and LCD (VLCD) supplies, and delivers RMS on/off voltages (e.g., Von(RMS) = 0.577 × VLCD in 1:4/1/3 mode) directly tied to discrimination ratio and contrast performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Display Drive Capability | Up to 4 backplanes and 32 segments - enables 16×7-segment, 8×14-segment, or 128-element graphics LCDs |
| Multiplex Modes | Static, 1:2, 1:3, or 1:4 - selected via command register; determines RAM row usage and output timing sequence |
| LCD Bias Configuration | 1/2 or 1/3 bias - sets internal voltage divider taps to achieve required discrimination ratio (e.g., D = 1.732 in 1:4/1/3) |
| I²C Interface Speed | 400 kHz - supports standard fast-mode I²C without external pull-up tuning for most microcontroller hosts |
| Supply Voltage Ranges | VDD = 1.8–5.5 V; VLCD = 2.5–6.5 V - allows direct interface to low-threshold or guest-host LCDs without level shifters |
| Display Memory | 32 × 4-bit static RAM - one-to-one mapping between RAM bits, segment outputs (S0–S31), and backplane rows (BP0–BP3) |
| Operating Temperature | −40 °C to +85 °C - qualified per AEC-Q100 for automotive dashboard and control panel use |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SDA (10) | I²C serial data line | Open-drain bidirectional bus node - requires external pull-up; handles command/data transfer and ACK/NACK |
| SCL (11) | I²C serial clock input | Master-generated clock synchronizing all I²C transactions; 400 kHz max rated frequency |
| OSC (15) | Oscillator enable control | Connect to VSS to activate internal RC oscillator; connect to VDD to enable external CLK input |
| CLK (13) | External clock input | Accepts TTL/CMOS clock signal when OSC = VDD - sets frame rate and timing base |
| A0–A2 (16–18) | Hardware subaddress inputs | Select device subaddress boundary (0–7) for segmented RAM access without software address management |
| SA0 (19) | I²C slave address bit | Configures LSB of 7-bit I²C address (0x70–0x77); enables multi-device bus topology |
| BP0–BP3 (22–25) | LCD backplane outputs | Time-multiplexed square-wave outputs - BP0–BP3 active in 1:4 mode; paired in lower-mux modes for drive strength |
| S0–S31 (26–48, 1–9) | LCD segment outputs | 32 dedicated CMOS drivers - directly connect to LCD segment electrodes; unused pins left open |
| VLCD (21) | LCD supply voltage | Independent analog rail - sets full-scale LCD drive amplitude; externally temperature-compensated if needed |
| VDD (14), VSS (20) | Digital supply and ground | Logic core power domain - decoupling required within 10 mm of pins per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Auto-incremented RAM addressing | Eliminates manual address tracking during bulk display updates - reduces host CPU overhead per byte written |
| Display memory bank switching | Enables double-buffered updates in static/1:2 modes - prevents partial-frame artifacts during dynamic content changes |

FAQ
What is the primary function of the PCF8562TT/S400/2,1 in an LCD system?
The PCF8562TT/S400/2,1 serves as a standalone LCD controller and driver IC that generates time-multiplexed backplane and segment waveforms, manages 32×4-bit display RAM, and handles I²C communication with the host microcontroller. It eliminates the need for external bias resistors or timing circuitry, directly driving LCDs with up to four backplanes and 32 segments - making it ideal for automotive and industrial segmented displays.
Is the PCF8562TT/S400/2,1 pin-compatible with other members of the PCF8562 family?
Yes - the PCF8562TT/S400/2,1 shares identical TSSOP48 pinout and electrical characteristics with all PCF8562TT variants (e.g., PCF8562TT/2,1, PCF8562TT/S400/2), including identical SDA, SCL, BP0–BP3, S0–S31, and control pin assignments. This ensures mechanical and functional interchangeability within the same PCB footprint across ordering variants.
How does the PCF8562TT/S400/2,1 handle display blinking without host processor involvement?
The PCF8562TT/S400/2,1 implements hardware-based blinking using its display RAM bank switching capability. In static or 1:2 multiplex modes, the blink-select command toggles between RAM banks at user-defined intervals - swapping displayed content without I²C traffic. This offloads blink animation entirely from the host MCU, reducing firmware complexity and bus utilization.
What are the key differences between PCF8562TT/S400/2,1 and its successor PCF85162T/Q900/1?
The PCF85162T/Q900/1 improves upon the PCF8562TT/S400/2,1 with ±8 kV HBM ESD protection (vs. ±4 kV), extended VLCD range up to 7 V, tighter I²C timing margins, and formal obsolescence mitigation per PCN202102010F01. While functionally compatible, PCF85162T/Q900/1 is designated for new automotive designs requiring long-term supply assurance beyond the PCF8562TT/S400/2,1 discontinuation timeline.
Can the PCF8562TT/S400/2,1 drive high-threshold twisted nematic (HTN) LCDs?
Yes - the PCF8562TT/S400/2,1 supports VLCD up to 6.5 V, enabling direct interface with high-threshold twisted nematic (HTN) and guest-host LCDs. Its internal voltage-follower buffers maintain stable bias ratios across load variations, and the selectable 1/2 or 1/3 bias configurations allow optimization of discrimination ratio (D) for contrast performance on HTN modules.
