C8051F340-GQ

C8051F340-GQ is a fully integrated mixed-signal system-on-a-chip MCU. The flash memory can be reprogrammed 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.

• Voltages from 3.6 to 5.25V supported using on-chip voltage regulator
• Integrated clock recovery; no external crystal required for full speed or low speed
• Provides breakpoints, single stepping, inspect/modify memory and registers
• Superior performance to emulation systems using ICE-chips, target pods, and sockets
• Pipelined instruction architecture; executes 70% of instructions in 1 or 2 system clocks
• 16-bit programmable counter array (PCA) with five capture/compare modules
• 48MIPS (peak), 64Kbyte flash memory, 4352 RAM, calibrated internal oscillator
• Low frequency oscillator, USB with 1K endpoint RAM, supply voltage regulator
• SMBus/I²C, enhanced SPI, 2 UARTs, 4 timers (16-bit)
• Temperature range from -40 to +85°C, TQFP48 package
