Mixed-Signal Byte-Programmable EPROM MCU

Silicon Laboratories 

C8051F336/7/8/9

Mixed-Signal Byte-Programmable EPROM MCU

Analog Peripherals

- 10-Bit ADC (‘F336/8 only)

• Up to 200 ksps

• Up to 20 external single-ended or differential inputs

• VREF from on-chip VREF, external pin or VDD

• Internal or external start of conversion source

• Built-in temperature sensor

- 10-Bit Current Output DAC (‘F336/8 only)

- Comparator

• Programmable hysteresis and response time

• Configurable as interrupt or reset source

On-Chip Debug

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

intrusive in-system debug (no emulator required)

- Provides breakpoints, single stepping,

inspect/modify memory and registers

- Superior performance to emulation systems using

ICE-chips, target pods, and sockets

- Low cost, complete development kit

Supply Voltage 2.7 to 3.6 V

- Built-in voltage supply monitor

High-Speed 8051 µC Core

- Pipelined instruction architecture; executes 70% of

instructions in 1 or 2 system clocks

- Up to 25 MIPS throughput with 25 MHz clock

- Expanded interrupt handler

Temperature Range: –40 to +85 °C

Memory

- 768 bytes internal data RAM (256 + 512)

- 16 kB Flash; In-system programmable in 512-byte

Sectors (512 bytes are reserved)

Digital Peripherals

- 21 or 17 Port I/O; All 5 V tolerant with high sink

current

- Pin-compatible with C8051F330 family of MCUs

- Hardware enhanced UART, SMBus™ (I2C compati-

ble), and enhanced SPI™ serial ports

- Four general purpose 16-bit counter/timers

- 16-Bit programmable counter array (PCA) with three

capture/compare modules and enhanced PWM

functionality

- Real time clock mode using timer and crystal

Clock Sources

- 24.5 MHz ±2% Oscillator

• Supports crystal-less UART operation

• Low-power suspend mode with fast wake time

- 80/20/40/10 kHz low-frequency, low-power

oscillator

- External oscillator: Crystal, RC, C, or clock

(1 or 2 pin modes)

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

in power saving modes

20 or 24-Pin QFN (4 x 4 mm)
