Supply Voltage: 0.9 to 3.6 V

-

One-cell mode supports 0.9–1.8 V operation

-

Two-cell mode supports 1.8–3.6 V operation

-

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

High-Speed 8051 µC Core

-

Pipe-lined instruction architecture; executes 70% of instructions

in 1 or 2 system clocks

-

25 MIPS peak throughput with 25 MHz clock

Expanded interrupt handler

Digital Peripherals

-

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

-

Hardware enhanced UART, SPI and SMBus™ serial ports

available concurrently

-

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

contents over full supply range; fast wakeup

-

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

10-Bit Analog to Digital Converter

-

Autonomous Burst Mode with 16-bit automatic averaging



accumulator

-

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

-

Four general purpose 16-bit counter/timers

-

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

pare modules and watchdog timer:

Two Comparators

Programmable hysteresis and response time

-

Configurable as interrupt or reset source

-

Low current (< 0.5 µA)

-

Up to 23 Capacitive Touch Sense inputs

Memory

-

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

•

Clock Sources

-

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

smaRTClock oscillator: 32.768 kHz crystal or self-oscillate

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

saving modes

-

External memory interface (multiplexed address/data)

On-Chip Debug

-

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

system debug (no emulator required)
