C8051F39x/37x
1. System Overview
C8051F39x/37x devices are fully integrated mixed-signal System-on-a-Chip MCUs. Highlighted features
are listed below. Refer to Section “2. Ordering Information” on page 20 for specific product feature selec-
tion and part ordering numbers.
High-speed pipelined 8051-compatible microcontroller core (up to 50 MIPS)
In-system, full-speed, non-intrusive debug interface (on-chip)
True 10-bit 500 ksps 20 or 16-channel single-ended/differential ADC with analog multiplexer
Two 10-bit Current Output DACs
Precision temperature sensor with ±2 °C absolute accuracy
Precision programmable 49 MHz internal oscillator
Low-power, low-frequency oscillator
16 kB of on-chip Flash memory
1024 bytes of on-chip RAM
Co-packaged with 512 bytes of EEPROM memory, accessible via I2C (C8051F37x)
Two SMBus/I2C, UART, and SPI serial interfaces implemented in hardware
Six 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
21 or 17 Port I/O
Low-power suspend mode with fast wake-up time
With on-chip Power-On Reset, VDD monitor, Watchdog Timer, and clock oscillator, the C8051F39x/37x
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 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.
The C8051F37x devices are specified for 1.8 to 3.6 V operation over the industrial temperature range (–40
to +85 °C), while the C8051F39x devices operate over an extended temperature range (-40 to +105 °C).
The C8051F392/3/6/7/8/9 are available in a 20-pin QFN package and the C8051F390/1/4/5 and
C8051F37x are available in a 24-pin QFN package. Both package options are lead-free and RoHS compli-
ant. See Section “2. Ordering Information” on page 20 for ordering information. Block diagrams are
included in Figure 1.1, Figure 1.2 and Figure 1.3.
