Product details
Overview
PCA9620U/5GA/Q1,01 from NXP Semiconductors is an AEC-Q100 Grade 2 qualified LCD segment driver IC for automotive and industrial applications. It drives up to 480-element multiplexed LCDs with 8 backplanes and 60 segments, supports internal charge-pump-generated VLCD up to 3×VDD2, operates from −40 °C to +105 °C, and communicates via a 400 kHz I²C-bus interface.
For engineers reviewing the PCA9620U/5GA/Q1,01 datasheet, PCA9620U/5GA/Q1,01 pinout, PCA9620U/5GA/Q1,01 application, or PCA9620U/5GA/Q1,01 equivalent, key selection criteria include its 8-backplane drive capability, programmable frame frequency (60–300 Hz), integrated temperature sensor with readout, selectable bias modes (1/2, 1/3, 1/4), and support for both internal and external VLCD supply configurations.
Technical Context
The PCA9620U/5GA/Q1,01 implements a dedicated LCD controller architecture with dual display RAM banks for concurrent write/read operations in static, duplex, and quadruplex drive modes. Its internal oscillator supports factory-calibrated frame frequencies with ±15% tolerance across full voltage and temperature ranges.
It integrates a programmable charge pump (2× or 3× VDD2), linear temperature compensation for VLCD, selectable inversion schemes (frame or line), and digital temperature filtering. The device uses I²C-bus addressing with A0/A1 pins and includes OTP calibration for VLCD accuracy, frame frequency, and temperature measurement.

FAQ
What is the package type of PCA9620U/5GA/Q1,01?
The PCA9620U/5GA/Q1,01 is supplied as bare die on unsawn wafer, featuring 80 bonding pads. It is not packaged in a plastic or ceramic enclosure and requires wire bonding or flip-chip integration into custom substrates or modules. This die form enables compact, thermally optimized implementations in space-constrained automotive and industrial systems.
Does PCA9620U/5GA/Q1,01 support external VLCD supply?
Yes, PCA9620U/5GA/Q1,01 supports external VLCD supply. When the internal charge pump is disabled via the charge-pump-ctrl command (CPE = 0), the VLCD pin becomes an input and accepts an externally generated voltage from 2.5 V to 9.0 V. This allows system-level optimization of power efficiency and noise isolation in applications where a dedicated DC-DC converter is already present.
How does the temperature compensation feature work in PCA9620U/5GA/Q1,01?
The PCA9620U/5GA/Q1,01 uses an on-die temperature sensor to measure die temperature and applies linear compensation to VLCD using four user-programmable slope coefficients (SLA–SLD). Compensation is enabled via the temp-msr-ctrl command (TCE = 1), and the sensor output (TD[7:0]) is readable via the temp-read command. This maintains stable LCD contrast across the full −40 °C to +105 °C operating range.
What is the default multiplex mode after Power-On Reset of PCA9620U/5GA/Q1,01?
After Power-On Reset (POR), the PCA9620U/5GA/Q1,01 defaults to 1:8 multiplex mode with 1/4 bias configuration. This setting is defined in the reset states table (Table 26) and corresponds to M[2:0] = 000 and B[1:0] = 00. The initialize command must be sent after POR to confirm or reconfigure these settings before enabling the display.
Can PCA9620U/5GA/Q1,01 drive 7-segment alphanumeric displays?
Yes, PCA9620U/5GA/Q1,01 can drive up to 60 individual 7-segment alphanumeric characters in static mode (1 backplane), or up to 30 such characters in 1:2 multiplex mode. Each character consumes 7 segments plus optional decimal points, and the device's 60-segment × 8-backplane architecture provides flexible allocation across numeric, symbol, and graphical elements within the 480-element limit.
