CP2400-C-GDI
Tested 128 Segment LCD Driver Die in Wafer Form
LCD Driver
- Controls up to 128 segments
- Supports static, 2-mux, 3-mux, and 4-mux displays
- On-chip bias generation with internal charge pump
- Low power blink capability
GPIO Expander
- Expands GPIO count by up to 36 pins
- GPIO pins may be configured to push-pull or open-
drain outputs with two drive levels. GPIO may also
be used as digital inputs
- Port Match Capability can wake up host controller
using interrupt pin
- 5 V Tolerant I/O
Real Time Clock, SmaRTClock
- Precision time keeping with 32.768 kHz watch crys-
tal; self-oscillate mode requires no external crystal;
accepts external 32 kHz CMOS clock
- 36-hour programmable counter with wake up alarm
- Can wake up the host controller using interrupt pin
- Low power (<1.5 µA)
256 Bytes RAM
- General purpose RAM expands the memory avail-
able to host controller.
16-bit Timers
l Two general purpose 16-bit timers
Clock Sources
- 20 MHz Internal oscillator
- Can be clocked from an external CMOS clock
Digital Bus Interface
- 4-wire SPI Interface (SPI device only) operates up
to 2.5 Mbps with synchronous external clock or up
to 1 Mbps with internal clock
- Dedicated RST and INT pins
- Optional CLK pin can be used as a CMOS clock
input.
- 2-wire SMBus/I²C interface (SMBus/I²C device
only) operates up to 400 kHz with internal clock
- Optional PWR pin (SMBus/I²C device only) places
the device in a low-power mode. SPI devices use
the NSS pin to place device in a low-power mode
Low Power
- 1.8–3.6 V operation with integrated LDO
- Ultra Low Power Mode w/ LCD (<3 µA typical)
- Shutdown current (0.05 µA typical)
Example Applications
- Handheld Equipment
- Utility Meters
- Thermostat Display
- Home Security Systems
Temperature Range: –40 to +85 °C
