C8051F335

Mixed-Signal ISP Flash MCU

Silicon Laboratories 

Analog Peripherals

- 10-Bit ADC (‘F330/2/4 only)

• Up to 200 ksps

• Up to 16 external single-ended or differential inputs

• VREF from internal VREF, external pin or VDD

• Internal or external start of conversion source

• Built-in temperature sensor

- 10-Bit Current Output DAC (‘F330 only)

- Comparator

• Programmable hysteresis and response time

• Configurable as interrupt or reset source

• Low current (0.4 µA)

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

- Typical operating current: 6.4 mA at 25 MHz;

9 µA at 32 kHz

- Typical stop mode current: 0.1 µA

Temperature Range: –40 to +85 °C

C8051F330/1/2/3/4/5

Mixed-Signal ISP Flash MCU

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

Memory

- 768 bytes internal data RAM (256 + 512)

- 8 kB (‘F330/1), 4 kB (‘F332/3), or 2 kB (‘F334/5)

Flash; In-system programmable in 512-byte Sec-

tors—512 bytes are reserved in the 8 kB devices

Digital Peripherals

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

- Hardware enhanced UART, SMBus™, and

enhanced SPI™ serial ports

- Four general purpose 16-bit counter/timers

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

capture/compare modules

- Real time clock mode using PCA or timer and exter-

nal clock source

Clock Sources

- Two internal oscillators:

• 24.5 MHz with ±2% accuracy supports crystal-less

UART operation

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

- 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
