C8051F392-A-GMR IC MCU 8BIT 16KB FLASH 20QFN

Description

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 without 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 compliant. 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.
