1.
The C8051F020/1/2/3 devices are fully integrated mixed-signal System-on-a-Chip MCUs with 64 digital I/O pins
(C8051F020/2) or 32 digital I/O pins (C8051F021/3). Highlighted features are listed below; refer to Table 1.1 for
specific product feature selection.
With on-chip VDD monitor, Watchdog Timer, and clock oscillator, the C8051F020/1/2/3 devices are truly stand-
alone System-on-a-Chip solutions. All analog and digital peripherals are enabled/disabled and configured by user
firmware. The FLASH memory can be reprogrammed even in-circuit, providing non-volatile data storage, and also
allowing field upgrades of the 8051 firmware.
On-board JTAG debug circuitry allows non-intrusive (uses no on-chip resources), full speed, in-circuit debugging
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 while debugging using JTAG.
Each MCU is specified for 2.7 V-to-3.6 V operation over the industrial temperature range (-45° C to +85° C). The
Port I/Os, /RST, and JTAG pins are tolerant for input signals up to 5 V. The C8051F020/2 are available in a 100-pin
TQFP package (see block diagrams in Figure 1.1 and Figure 1.3). The C8051F021/3 are available in a 64-pin TQFP
package (see block diagrams in Figure 1.2 and Figure 1.4).
