CP2400

CP2400/1/2/3 128/64 S EGMENT L C D D RIVER LCD Driver Controls Digital Bus Interface 4-wire up to 128 segments (48-pin packages) or 64 segments (32-pin package) Supports static, 2-mux, 3-mux, and 4-mux displays On-chip bias generation with internal charge pump Low power blink capability SPI Interface operates up to 2.5 Mbps with synchronous external clock or up to 1 Mbps with internal clock (CP2400/2 only). GPIO Expander Expands GPIO count by up to 36 pins (48-pin packages) or 20 pins (32-pin package) GPIO pins may be configured to push-pull or open-drain outputs with two drive levels. GPIO may also be used as digital inputs (CP2400/1/2/3 pullups included) Port Match Capability can wake up host controller using interrupt pin 5 V Tolerant I/O SMBus/I2C Interface operates up to 400 kHz with internal clock (CP2401/3 only). Dedicated RST and INT pins. Optional CLK pin can be used as a CMOS clock input. 2-wire Optional PWR pin (SMBus/I2C devices only) places the device in a low power mode. SPI devices use the NSS pin to place the device in a low power mode. Low Power 1.8–3.6 Ultra V operation with integrated LDO Low Power Mode w/ LCD (
