Product Summary

With on-chip Power-On Reset, VDD monitor, Voltage Regulator, Watchdog Timer, and clock oscillator, the C8051F320-GQ is a truly stand-alone System-on-a-Chip solution. The FLASH memory can be reprogrammed in-circuit, providing non-volatile data storage, and also allowing field upgrades of the 8051 firmware. The C8051F320-GQ is specified for 2.7 V- to-3.6 V operation over the industrial temperature range (-40℃ to +85℃). The Port I/O and /RST pins are tolerant of input signals up to 5 V. The C8051F320-GQ is available in a 32-pin LQFP or a 28-pin MLP package.

Parametrics

C8051F320-GQ absolute maximum ratings: (1)Ambient temperature under bias: -55 to 125 ℃; (2)Storage Temperature: -65 to 150 ℃; (3)Voltage on any Port I/O Pin or /RST with respect to GND: -0.3 to 5.8 V; (4)Voltage on VDD with respect to GND: -0.3 to 4.2 V; (5)Maximum Total current through VDD and GND: 500 mA; (6)Maximum output current sunk by /RST or any Port pin: 100 mA.
