Overview
C8051F97x Low Power Capacitive Sensing MCU with up to 32 kB of Flash Low Power Consumption - 200 µA/MHz in active mode (24.
5 MHz clock) - 2 µs wakeup time - 55 nA sleep mode with brownout detector - 280 nA sleep mode with LFO - 600 nA sleep mode with external crystal Capacitance Sense Interface - Supports buttons, sliders, wheels, and proximity sensing - Fast 40 µs per channel conversion time - 16-bit resolution, up to 43 input channels - Auto scan and wake-on-touch - Auto-accumulate up to 64x samples 10-Bit Analog-to-Digital Converter - Up to 43 external pin input channels, up to 300 ksps - Internal VREF or external VREF supported Clock Sources - Internal oscillators: 24.
5 MHz, ±2% accuracy supports UART - SmaRTClock oscillator: 32 kHz Crystal or internal LFO - Can switch between clock sources on-the-fly; useful in implementing various power-saving modes operation; 20 MHz low power oscillator requires very little bias current.
External oscillator: Crystal, RC, C, or CMOS Clock High-Speed CIP-51 µC Core - Efficient, pipelined instruction architecture - Up to 25 MIPS throughput with 25 MHz clock - Uses standard 8051 instruction set - Expanded interrupt handler - 1-cycle 16 x 16 MAC Engine - 7-channel Direct Memory Access (DMA) module Memory - Up to 32 kB flash - Flash is in-system programmable in 512-Byte sectors - Up to 8 kB RAM General-Purpose I/O - Up to 43 pins with high sink current and programmable drive - Crossbar-enabled Timer/Counters and PWM - 4 general purpose 16-bit timer/counters - 16-bit Programmable Counter Array (PCA) with three channels of PWM, capture/compare, or frequency output capability, and watchdog timer Supply Voltage: 1.
8 to 3.
6 V - Built-in LDO regulator allows a high analog supply voltage and low digital core voltage - 2 supply monitors (brownout detector) for sleep and active modes On-Chip Debug - On-chip debug circuitry facilitates full speed, non-intrusive insystem debug (no emulator required) Provides breakpoints, single stepping, ...
