1. SYSTEM OVERVIEW

C8051F320/1 devices are fully integrated mixed-signal System-on-a-Chip MCUs. Highlighted features are listed

below. Refer to Table 1.1 for specific product feature selection.

• High-speed pipelined 8051-compatible microcontroller core (up to 25 MIPS)

• In-system, full-speed, non-intrusive debug interface (on-chip)

• Universal Serial Bus (USB) Function Controller with eight flexible endpoint pipes, integrated transceiver, and

1k FIFO RAM

• Supply Voltage Regulator (5V-to-3V)

• True 10-bit 200 ksps 17-channel single-ended/differential ADC with analog multiplexer

• On-chip Voltage Reference and Temperature Sensor

• On-chip Voltage Comparators (2)

• Precision programmable 12 MHz internal oscillator and 4x clock multiplier

• 16k bytes of on-chip FLASH memory

• 2304 total bytes of on-chip RAM (256 + 1k + 1k USB FIFO)

• SMBus/I2C, Enhanced UART, and Enhanced SPI serial interfaces implemented in hardware

• Four general-purpose 16-bit timers

• Programmable Counter/Timer Array (PCA) with five capture/compare modules and Watchdog Timer function

• On-chip Power-On Reset, VDD Monitor, and Missing Clock Detector

• 25/21 Port I/O (5V tolerant)

With on-chip Power-On Reset, VDD monitor, Voltage Regulator, Watchdog Timer, and clock oscillator,

C8051F320/1 devices are truly stand-alone System-on-a-Chip solutions. The FLASH memory can be reprogrammed

in-circuit, providing non-volatile data storage, and also allowing field upgrades of the 8051 firmware. User software

has complete control of all peripherals, and may individually shut down any or all peripherals for power savings.

The on-chip Silicon Labs 2-Wire (C2) Development Interface allows non-intrusive (uses no on-chip resources), full

speed, in-circuit debugging using the production MCU installed in the final application. This debug logic supports

inspection and modification of memory and registers, setting breakpoints, single stepping, run and halt commands.

All analog and digital peripherals are fully functional while debugging using C2. The two C2 interface pins can be

shared with user functions, allowing in-system debugging without occupying package pins.

Each device is specified for 2.7 V-to-3.6 V operation over the industrial temperature range (-40°C to +85°C). (Note

that 3.0 V-to-3.6 V is required for USB communication.) The Port I/O and /RST pins are tolerant of input signals up

to 5 V. C8051F320/1 are available in a 32-pin LQFP or a 28-pin MLP package.
