The C8051F04x family of devices are fully integrated mixed-signal System-on-a-Chip MCUs with 64 digital
I/O pins (C8051F040/2/4/6) or 32 digital I/O pins (C8051F041/3/5/7), and an integrated CAN 2.0B control-
ler. Highlighted features are listed below; refer to Table 1.1 for specific product feature selection.

With on-chip V
stand-alone System-on-a-Chip solutions. All analog and digital peripherals are enabled/disabled and con-
figured 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 pro-
gramming and 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 to +85 °C).
The Port I/Os, /RST, and JTAG pins are tolerant for input signals up to 5 V. The C8051F040/2/4/6 are avail-
able in a 100-pin TQFP and the C8051F041/3/5/7 are available in a 64-pin TQFP.
