C8051F38x

Full Speed USB Flash MCU Family

Analog Peripherals

10-Bit ADC (C8051F380/1/2/3 only)

- Up to 500 ksps

- Built-in analog multiplexer with single-ended and differential mode

- VREF from external pin, internal reference, or VDD

- Built-in temperature sensor

- External conversion start input option

Two Comparators

Internal Voltage Reference (C8051F380/1/2/3 Only)

Brown-Out Detector and POR Circuitry

USB Function Controller

- USB specification 2.0 compliant

- Full-speed (12 Mbps) or low-speed (1.5 Mbps) operation

- Integrated clock recovery; no external crystal required for full-speed or

low-speed

- Supports eight flexible endpoints

- 1 kB USB buffer memory

- Integrated transceiver; no external resistors required

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 reg-

isters

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

pods, and sockets

Supply Voltage: 1.8 to 3.6 V

- Voltages from 2.7 to 5.25 V supported using on-chip voltage regulators

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 48 MIPS operation

- Expanded interrupt handler

Memory

- 4352 or 2304 Bytes RAM

- 64 or 32 kB Flash; In-system programmable in 512-byte sectors

Digital Peripherals

- 40/25 Port I/O; All 5 V tolerant with high sink current

- Hardware enhanced SPI™, two I²C/SMBus™, and two enhanced UART

serial ports

- Six general purpose 16-bit counter/timers

- 16-bit programmable counter array (PCA) with five capture/compare

modules

- External Memory Interface (EMIF)

- Clock Sources

Clock Sources

- Internal Oscillator: ±0.25% accuracy with clock recovery enabled. Sup-

ports all USB and UART modes

- External Oscillator: Crystal, RC, C, or clock (1 or 2 Pin modes)

- Low Frequency (80 kHz) Internal Oscillator

- Can switch between clock sources on-the-fly

Package

- 48-pin TQFP (C8051F380/2/4/6)

- 32-pin LQFP (C8051F381/3/5)

- 5x5 mm 32-pin QFN (C8051F381/3/5)
