System Overview

The C8051F52x/F52xA/F53x/F53xA family of devices are fully integrated, low power, mixed-signal systemon-a-chip MCUs. Highlighted features are listed below. Refer to Table 1.1 for specific product feature selection.

 

 

■ High-speed pipelined 8051-compatible microcontroller core (up to 25 MIPS)

■ In-system, full-speed, non-intrusive debug interface (on-chip)
■ True 12-bit 200 ksps ADC with analog multiplexer and up to 16 analog inputs
■ Precision programmable 24.5 MHz internal oscillator that is within ±0.5% across the temperature range and for VDD voltages greater than or equal to the on-chip voltage regulator minimum output at the low setting. The oscillator is within +1.0% for VDD voltages below this minimum output setting.
■ Up to 7680 bytes of on-chip Flash memory
■ 256 bytes of on-chip RAM
■ Enhanced UART, and SPI serial interfaces implemented in hardware
■ LIN 2.1 peripheral (fully backwards compatible, master and slave modes)
■ Three general-purpose 16-bit timers
■ Programmable Counter/Timer Array (PCA) with three capture/compare modules and Watchdog Timer function
■ On-chip Power-On Reset, VDD Monitor, and Temperature Sensor
■ On-chip Voltage Comparator
■ Up to 16 Port I/O
