C8051F340

USB, 48 MIPS, 64 kB Flash, 10-Bit ADC, 48-Pin Mixed-Signal MCU

Analog Peripherals

10-Bit ADC

- ±1 LSB INL; no missing codes

- Programmable throughput up to 200 ksps

- Up to 17 external inputs; programmable as single-ended or differential

- Built-in temperature sensor (±3 °C)

Two Comparators
Internal Voltage Reference: 2.4 V
POR/Brown-out Detector

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 either full-

speed or low-speed operation

- Supports eight flexible endpoints

- Dedicated 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, registers, and USB memory

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

pods, and sockets

Temperature Range: –40 to +85 °C

High-Speed 8051 µC Core

system clocks

- Up to 48 MIPS throughput with 48 MHz Clock

- Expanded interrupt handler

Memory

- 4352 bytes data RAM (256 + 4 kB)

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

are reserved)

- External parallel data memory interface

Digital Peripherals

- 40 port I/O; all are 5 V tolerant

- Hardware SMBus™ (I

available concurrently

2

C™ compatible), SPI™, and 2 UART serial ports

- 4 general-purpose 16-bit counter/timers

- Programmable 16-bit counter array with 5 capture/compare modules

Clock Sources

- Internal oscillator: 0.25% accuracy with clock recovery enabled;

supports all USB and UART modes

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

- On-chip clock multiplier: up to 48 MHz

Voltage Regulator
