Product details
Overview
PCA9620H/Q900/1,51 from NXP Semiconductors is a high-drive LCD segment driver IC for automotive and industrial applications. It drives up to 8 backplanes and 60 segments (480 elements), supports static/multiplexed LCDs, features an integrated charge pump generating up to 3×VDD2 for VLCD, and communicates via a 400 kHz I²C-bus interface.
For engineers reviewing the PCA9620H/Q900/1,51 datasheet, PCA9620H/Q900/1,51 pinout, PCA9620H/Q900/1,51 application, or PCA9620H/Q900/1,51 equivalent, key selection factors include AEC-Q200 Grade 2 compliance, programmable frame frequency (60–300 Hz), selectable bias/mux modes, internal temperature sensor with readout, and linear temperature compensation of VLCD.
Technical Context
The PCA9620H/Q900/1,51 implements a dedicated LCD controller architecture with dual-bank display RAM (480-bit), auto-incremented addressing, and independent input/output bank selection for flicker-free updates. Its internal oscillator (factory-calibrated ±15% over −40 °C to +105 °C) feeds both the frame timing generator and charge pump clock.
It supports line or frame inversion for DC voltage cancellation, configurable via I²C command, and integrates a digital temperature sensor with optional filtering. The charge pump operates at ~1 MHz or ~500 kHz, selectable per application power/noise trade-offs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Display Capacity | Drives up to 8 backplanes × 60 segments = 480 LCD elements; supports static, 1:2, 1:4, 1:6, or 1:8 multiplexing. |
| I²C Interface Speed | 400 kHz maximum; enables low-overhead communication with microcontrollers without requiring additional GPIOs. |
| Frame Frequency Range | Programmable in 10 Hz steps from 60 Hz to 300 Hz; factory-calibrated ±15% across full temperature/voltage range. |
| LCD Supply (VLCD) | Internally generated up to 3×VDD2 (VDD2 = 2.5–5.5 V); externally supplied range: 2.5 V to 9.0 V for high-threshold automotive TN LCDs. |
| Operating Temperature | −40 °C to +105 °C; qualified to AEC-Q200 Grade 2 for under-hood automotive instrument clusters and climate controls. |
| Power Supply Range | VDD1 and VDD2: 2.5 V to 5.5 V each; enables single-supply operation or split-rail flexibility for analog/digital domains. |
| Temperature Sensing | Integrated on-die sensor with digital readout (TD[7:0]) and optional digital filter; used for linear VLCD compensation. |
Pinout & Package
LQFP80 package (SOT315-1), 12 mm × 12 mm × 1.4 mm body, 0.5 mm pitch, with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S0–S59 | LCD segment outputs | 60 dedicated high-drive outputs; sink current capability sufficient for automotive-grade LCD contrast at 9 V VLCD. |
| BP0–BP7 | LCD backplane outputs | 8 backplane drivers supporting 1:8 multiplex mode; configured via set-MUX-mode command. |
| VLCD | LCD supply voltage terminal | Output when internal charge pump enabled; input when external VLCD supplied; requires decoupling capacitor (≥100 nF). |

| VSS | Ground reference | Common return for all analog/digital/charge pump circuits; low-impedance connection critical to minimize VLCD ripple. |
| SCL, SDA | I²C-bus interface | Standard open-drain bidirectional signals; support 400 kHz operation with standard pull-ups; no level-shifting required. |
| A0, A1 | I²C slave address select | Two pins configure 4 unique I²C addresses (0x38–0x3B), enabling multiple PCA9620H devices on same bus. |
| CLK | Oscillator I/O | Configurable as internal oscillator output or external clock input; controlled by oscillator-ctrl command. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pump | Generates VLCD up to 3×VDD2 internally; eliminates need for external DC-DC converter in space-constrained automotive modules. |
| Selectable inversion scheme | Line or frame inversion configurable via I²C; frame inversion reduces power consumption but may introduce flicker risk at low frame rates. |
| Display memory bank switching | Independent input/output bank selection (up to 8 banks) enables seamless background RAM updates without display artifacts. |
| Programmable bias configuration | 1/2, 1/3, or 1/4 bias modes selectable per application; matches common LCD panel requirements without external resistor networks. |
| On-chip calibration | Factory-trimmed oscillator frequency and VLCD generation; ensures stable frame timing and contrast across temperature and voltage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LCD segment driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCF8576CT/1/1,118 | 40-segment × 4-backplane (160 elements); no internal charge pump; requires external VLCD supply; max frame frequency 120 Hz. | Lower element count and no temperature compensation; suitable only for simpler, lower-voltage industrial displays. | Choose when driving smaller LCDs (<160 elements) and external VLCD is already available; not suitable for automotive AEC-Q200 systems. |
| MAX6955ATL+T | 28-segment × 8-backplane (224 elements); integrated charge pump; I²C interface; no temperature sensor or VLCD compensation. | Lacks on-chip temperature sensing and linear VLCD compensation; limited to −40 °C to +85 °C operation. | Consider for cost-sensitive consumer HMIs where full automotive temperature range and contrast stability are not required. |

FAQ
What is the maximum LCD element count supported by the PCA9620H/Q900/1,51?
The PCA9620H/Q900/1,51 supports up to 480 LCD elements - achieved with 8 backplanes and 60 segments. This enables configurations such as 60 seven-segment characters, 30 fourteen-segment characters, or arbitrary graphics layouts within that element limit. The device's 480-bit display RAM stores all segment states directly.
Does the PCA9620H/Q900/1,51 require external capacitors for its internal charge pump?
Yes, the PCA9620H/Q900/1,51 requires external capacitors on VDD1, VDD2, and VLCD pins - minimum 100 nF each. Larger VLCD capacitors reduce ripple but increase charge time. When VDD1 and VDD2 are externally tied, a single 200 nF capacitor suffices. Insufficient decoupling causes VLCD ripple and potential display flicker.
How does the PCA9620H/Q900/1,51 handle temperature variation in automotive applications?
The PCA9620H/Q900/1,51 integrates an on-die temperature sensor with digital readout (TD[7:0]) and supports linear temperature compensation of VLCD. When enabled, this feature dynamically adjusts the LCD supply voltage to maintain consistent contrast across the full −40 °C to +105 °C operating range, meeting AEC-Q200 Grade 2 requirements.
Can the PCA9620H/Q900/1,51 operate with an external VLCD supply?
Yes, the PCA9620H/Q900/1,51 supports external VLCD supply from 2.5 V to 9.0 V. In this mode, the internal charge pump must be disabled via the charge-pump-ctrl command, and VLCD pin becomes an input. This configuration is used when higher efficiency or tighter VLCD regulation is needed beyond the internal pump's capability.
What I²C address options are available for the PCA9620H/Q900/1,51?
The PCA9620H/Q900/1,51 provides four I²C slave addresses (0x38–0x3B) selected by A0 and A1 pins. This allows up to four PCA9620H/Q900/1,51 devices on the same I²C bus - useful in multi-display systems like center consoles with separate cluster, radio, and climate panels.
