50 MIPS, 8 kB Flash, 16-Bit ADC, 28-Pin Mixed-Signal MCU

Analog Peripherals

16-Bit ADC

- 0.0015% nonlinearity

- Programmable throughput up to 1 ksps

- 8 external inputs; programmable as single-ended or differential

- Programmable amplifier gain: 128, 64, 32, 16, 8, 4, 2, 1

- Data-dependent windowed interrupt generator

- Built-in temperature sensor (±3 °C)

Two 8-Bit Current DACs
Comparator

- 16 Programmable hysteresis values and response time

- Configurable to generate interrupts or reset

- Low current (0.4 µA)

Internal Voltage Reference
VDD Monitor/Brown-out Detector

On-Chip Debug

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

debug (no emulator required)

- Provides breakpoints, single stepping, watchpoints

- Inspect/modify memory, registers, and stack

- Superior performance to emulation systems using ICE-chips, target

pods, and sockets

Supply Voltage: 2.7 to 3.6 V

- Typical operating current: 17 mA at 50 MHz

16 µA at 32 kHz

- Typical stop mode current: <0.1 µA

Temperature Range: –40 to +85 °C

High-Speed 8051 µC Core

- Pipelined instruction architecture; executes 70% of instructions in 1 or 2

system clocks

- Up to 50 MIPS throughput with 50 MHz clock

- Expanded interrupt handler

Memory

- 768 bytes data RAM

- 8 kB Flash; in-system programmable in 512 byte sectors (512 bytes are

reserved)

Digital Peripherals

- 17 port I/O; all 5 V tolerant

- Hardware SMBus™ (I2C™ compatible), SPI™, and UART serial ports

available concurrently

- 16-bit programmable counter array with three capture/compare modules,

WDT

- 4 general-purpose 16-bit counter/timers

- Realtime clock mode using PCA or timer and external clock source

Clock Sources

- Internal oscillator: 24.5 MHz, 2% accuracy supports UART operation

- External oscillator: Crystal, RC, C, or clock (1 or 2 pin modes)

- 2x clock multiplier to achieve 50 MHz internal clock

- Can switch between clock sources on-the-fly

Package

- 28-pin QFN (lead-free package)
