C8051F320 Single Chip Development Board Mixed Signal ISPFLASH Microcontroller Module Board CJMCU-5132 UART 5V Single Chip Microcomputer

USB Function Controller USB specification 2.0 compliant Full speed (12 Mbps) or low speed ( 1.5 Mbps) operation Integrated clock recovery; no external crystal required for full speed or low speed Supports eight flexible endpoints 1 kB USB buffer memory Integrated transceiver; no external resistors required On-Chip Debug On-chip debug circuitry facilitates full speed, non-intrusive in-system debug (no emulator required) Provides breakpoints, single stepping, inspect/modify memory and registers Superior performance to emulation systems using ICE-chips, target pods, and sockets
Voltage Regulator Input: 4.0 to 5.25 V High Speed 8051 µC Core Pipelined instruction architecture; executes 70% of instructions in 1 or 2 system clocks Up to 25 MIPS throughput with 25 MHz clock Expanded interrupt handler Memory 2304 bytes internal RAM (1k + 256 + 1k USB FIFO) 16 kB Flash; In-system programmable in 512-byte sectors Digital Peripherals 25/21 Port I/O; All 5V tolerant with high sink current Hardware enhanced SPI, enhanced UART, and SMBus serial ports Four general purpose 16-bit counter/timers 16-bit programmable counter array (PCA) with five capture/compare modules Real time clock mode using external clock source and PCA or timer
Clock Sources Internal Oscillator: 0.25 % accuracy with clock recovery enabled. Supports all USB and UART modes
External oscillator: Crystal, RC, C, or Clock (1 or 2 pin modes) Can switch between clock sources on-the-fly; useful in power saving strategies
Temperature Range: 40 to +85 °C
