C8051F300

Mixed Signal ISP Flash MCU Family

Unspecified 

Analog Peripherals

- 8-Bit ADC ('F300/2 only)

• Up to 500 ksps

• Up to 8 external inputs

• Programmable amplifier gains of 4, 2, 1, & 0.5

• VREF from external pin or VDD

• Built-in temperature sensor

• External conversion start input

- Comparator

• Programmable hysteresis and response time

• Configurable as interrupt or reset source

• Low current (<0.5 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

- Complete development kit

Supply Voltage 2.7 to 3.6 V

- Typical operating current: 5 mA @ 25 MHz;

11 µA @ 32 kHz

- Typical stop mode current: 0.1 µA

- Temperature range: –40 to +85 °C

C8051F300/1/2/3/4/5

Mixed Signal ISP Flash MCU Family

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

- 256 bytes internal data RAM

- Up to 8 kB Flash; In-system programmable in 512

byte sectors

Digital Peripherals

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

- Hardware enhanced UART and SMBus™ serial

ports

- Three 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

external clock source

Clock Sources

- Internal oscillator: 24.5 MHz with ±2% accuracy

supports UART operation

- 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

11-Pin Quad Flat No-Lead (QFN) Package

(Lead-free package available)

- 3x3 mm PWB footprint
