Product Introduction

The series is an 8051 core, MCS-51-compatible 1T command system, a general-purpose IO type 8-bit chip, operating at up to 48MHz.

Products Features

? Features a maximum of 16KB of program area, 256B of RAM space, 1KB of XRAM, and 1KB of non-volatile data area.

? With four oscillation modes, the system clock can be switched freely between the four clock sources, and the external oscillator stop detection.

? Support normal, idle, sleep three working modes, can effectively reduce power consumption.

? Built-in low-voltage reset LVR, low-voltage monitoring LVD, watchdog overflow reset and other protection settings can effectively improve the reliability of system operation.

? It has a variety of interrupt sources such as external interrupts, timer interrupts and other peripheral interrupts, which can respond to external events in a timely manner and improve the utilization of MCUs.

? 9 timers, can achieve timing, counting, input capture, output comparison, timed wake-up, baud rate generator and other functions.

? Supports up to 24COM and 24SEG LED drives

? Supports up to 24COM and 24SEG LCD drives

? 4 channels of 16-bit PWM, support independent, complementary, synchronous three modes of output, with hardware brake function and brake recovery, dead zone control function, mask output and other functions.

? With 1 I2C, 1 SPI, 1 UART communication module, it can realize data transmission between the system and other devices.

? Features a high accuracy 12-bit ADC with selectable internal reference voltage, up to 2 comparators, built-in temperature sensors, and richer analog functions.
