C8051F388/9/A/B
1. System Overview
C8051F388/9/A/B 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 48 MIPS)
 In-system, full-speed, non-intrusive debug interface (on-chip)
 Supply Voltage Regulator
 True 10-bit 500 ksps differential / single-ended ADC with analog multiplexer
 On-chip Voltage Reference and Temperature Sensor
 On-chip Voltage Comparators (2)
 Precision internal calibrated 48 MHz internal oscillator
 Internal low-frequency oscillator for additional power savings
 Up to 64 kB of on-chip Flash memory
 Up to 4352 Bytes of on-chip RAM (256 + 4 kB)
 External Memory Interface (EMIF) available on 48-pin versions.
 2 I²C/SMBus, 2 UARTs, 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, V_DD Monitor, and Missing Clock Detector
 Up to 40 Port I/O (5 V tolerant)
With on-chip Power-On Reset, V_DD monitor, Voltage Regulator, Watchdog Timer, and clock oscillator,
C8051F388/9/A/B 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 with-
out occupying package pins.
Each device is specified for 2.7–5.25 V operation over the industrial temperature range (–40 to +85 °C).
For voltages above 3.6 V, the on-chip Voltage Regulator must be used. The Port I/O and RST pins are tol-
erant of input signals up to 5 V. C8051F388/9/A/B devices are available in 48-pin TQFP, 32-pin LQFP, or
32-pin QFN packages. See Table 1.1, “Product Selection Guide,” on page 16 for feature and package
choices.
