System Overview
The C8051F2xx is a family of fully integrated, mixed-signal System on a Chip MCU's available with a true
12-bit ('F206) multi-channel ADC, 8-bit multi-channel ADC ('F220/1/6 and 'F206), or without an ADC
('F230/1/6). Each model features an 8051-compatible microcontroller core with 8 kB of Flash memory.
There are also UART and SPI serial interfaces implemented in hardware (not "bit-banged" in user soft-
ware). Products in this family feature 22 or 32 general purpose I/O pins, some of which can be used for
assigned digital peripheral interface. Any pins may be configured for use as analog input to the analog-to-
digital converter ('F220/1/6 and 'F206 only). (See the Product Selection Guide in Table 1.1 for a quick ref-
erence of each MCUs' feature set.)
Other features include an on-board
VDD monitor, WDT, and clock oscillator. On-board Flash memory can
be reprogrammed in-circuit, and may also be used for non-volatile data storage. Integrated peripherals
can also individually shut down any or all of the peripherals to conserve power. All parts have 256 bytes of
SRAM. Also, an additional 1024 bytes of RAM is available in the 'F206/226/236.
On-board JTAG debug support allows non-intrusive (uses no on-chip resources), full speed, in-circuit
debug using the production MCU installed in the final application. This debug system supports inspection
and modification of memory and registers, setting breakpoints, watchpoints, single stepping, run and halt
commands. All analog and digital peripherals are fully functional when emulating using JTAG.
Each MCU is specified for 2.7 to 3.6 V operation over the industrial temperature range (–45 to +85 °C) and
is available in the 48-pin TFQP and 32-pin LFQP. The Port I/Os are tolerant for input signals up to 5 V.
