C8051F920

Single/Dual Battery, 0.9-3.6 V, 32 kB, smaRTClock, 10-Bit ADC MCU

Supply Voltage: 0.9 to 3.6 V

High-Speed 8051 µC Core

One-cell mode supports 0.9–1.8 V operation

Pipe-lined instruction architecture; executes 70% of instructions

in 1 or 2 system clocks

Two-cell mode supports 1.8–3.6 V operation

25 MIPS peak throughput with 25 MHz clock

Built-in dc-dc converter with 1.8 –3.3 V output (65 mW max) for

use in one-cell mode; can supply external devices

Expanded interrupt handler

Typical sleep mode current < 0.1 µA; retains state and RAM-

contents over full supply range; fast wakeup

Digital Peripherals

24 port I/O; All 5 V tolerant with programmable drive strength

2 built-in brown-out detectors cover sleep and active modes

Hardware enhanced UART, SPI and SMBus™ serial ports

available concurrently

10-Bit Analog to Digital Converter

Up to 300 ksps

Low power 32-bit smaRTClock (0.5 uA) operates down to 0.9V

Up to 23 external inputs

Four general purpose 16-bit counter/timers

External pin or internal VREF (no external capacitor required)

Built-in temperature sensor

16-bit programmable counter array (PCA) with six capture/com-

pare modules and watchdog timer:

•

8, 9, 10, 11, or 16-bit PWM

Rising/falling edge capture

Frequency output

External conversion start input option

Autonomous Burst Mode with 16-bit automatic averaging 

accumulator

Software timer

Two Comparators

Clock Sources

Programmable hysteresis and response time

Configurable as interrupt or reset source

Low current (< 0.5 µA)

Precision internal oscillators: 24.5 MHz with ±2% accuracy sup-

ports UART operation; spread-spectrum mode for reduced EMI

Low power internal oscillator: 20 MHz

External oscillator: Crystal, RC, C, CMOS clock

Up to 23 Capacitive Touch Sense inputs

smaRTClock oscillator: 32.768 kHz crystal or self-oscillate

Memory

Can switch between clock sources on-the-fly; useful in power

saving modes

4352 bytes internal data RAM (256 + 4K)

32 kB bytes Flash; In-system programmable in 1024-byte 

sectors; Full read/write/erase functionality over the entire

supply range

Ultra-Small Package Options

32-pin QFN (5x5 mm)

External memory interface (multiplexed address/data)

32-pin LQFP (9x9 mm)

On-Chip Debug

Temperature Range: –40 to +85 °C

On-chip debug circuitry facilitates full speed, non-intrusive in-

system debug (no emulator required)
