1. System Overview

C8051F300/1/2/3/4/5 devices are fully integrated mixed-signal system-on-a-chip MCUs. Highlighted fea-

tures are listed below. Refer to Table 1.1 on page 16 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)

• True 8-bit 500 ksps 11-channel ADC with programmable gain pre-amplifier and analog multiplexer

(C8051F300/2 only)

• Precision programmable 25 MHz internal oscillator

• Up to 8 kB of on-chip Flash memory

• 256 bytes of on-chip RAM

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

• Three general-purpose 16-bit timers

• Programmable counter/timer array (PCA) with three capture/compare modules and watchdog timer

function

• On-chip power-on reset, VDD monitor, and temperature sensor

• On-chip voltage comparator

• Byte-wide I/O port (5 V tolerant)

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

C8051F300/1/2/3/4/5 devices are truly stand-alone System-on-a-Chip solutions. The Flash memory can

be reprogrammed even 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 Laboratories 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 with-

out occupying package pins.

Each device is specified for 2.7 to 3.6 V operation over the industrial temperature range (–45 to +85 °C).

The Port I/O and /RST pins are tolerant of input signals up to 5 V. The C8051F300/1/2/3/4/5 are available

in the 11-pin QFN package (also referred to as MLP or MLF package) shown in Figure 4.2.
