WT51F516

The WT51F516 is a high-performance 8-bit Microcontroller, which incorporates the 1T 8052 8-bit CPU operating up to 12 MHz. This chip has 16K bytes and 512 bytes SRAM. Its peripherals include 8-channel 10-bit ADC, one slave I2C, one master/slave SPI, UART, four 10-bit PWMs, Hardware CEC, H/W universal IR receiver, Real Time Clock (RTC), Analog Comparator, Temperature Sensor, and Watchdog Timer (WDT). This chip also provides the capability to emulate E2PROM by using the embedded flash memory. Power down mode and embedded ICE/ISP are also provided as well. The WT51F516 is suitable for a wide range of applications, including wireless applications such as Zigbee/RF4CE (one-to-one), consumer electronics such as helicopter model remote/motor control, home appliances, industrial control, LED lighting control, medical equipments, and PC peripherals.
