STC12C5A16S2 - Brand New STMicroelectronics IC Chips
-
Description
STC12C5A16S2 is a single-chip microcontroller produced by STC MCU Limited. It is based on the high-performance 1T architecture 80C51 CPU. With its enhanced kernel, the STC12C5A16S2 executes instructions in 1~6 clock cycles, which is about 6~7 times faster than a standard 8051 device. It has a fully compatible instruction set with the industrial-standard 80C51 series microcontroller. The STC12C5A16S2 supports In-System-Programming (ISP) and In-Application-Programming (IAP) to allow users to upgrade the program and data while the microcontroller is in operation. It retains all the features of the standard 80C51 and provides additional I/O ports, interrupt structure, ADC, UARTs, on-chip crystal oscillator, PCA and PWM, SPI, and a one-time enabled Watchdog Timer.
Specifications and features
• Enhanced 80C51 Central Processing Unit, 1T per machine cycle, faster 6~7 times than the rate of a standard 8051. • Operating voltage range: 5.5V ~ 3.5V or 2.2V ~ 3.6V (STC12LE5A60S2). • Operating frequency range: 0- 35MHz, equivalent to standard 8051: 0~420MHz. • On-chip 8/16/20/32/40/48/52/56/60/62K FLASH program memory with flexible ISP/IAP capability. • On-chip 1280 byte RAM: 256 byte scratch-pad RAM and 1024 bytes of auxiliary RAM. • Capable of addressing up to 64K bytes of external RAM. • Dual Data Pointer (DPTR) to speed up data movement. • Code protection for flash memory access. • Excellent noise immunity, very low power consumption. • Four 16-bit timer/counters, compatible with Timer0/Timer1 of standard 8051, 2-channel PCA can be available as two timers. • 10 vector-address, 4-level priority interrupt capability. • One enhanced UART with hardware address-recognition and frame-error detection function. • Secondary UART with self baud-rate generator. • One 15-bit Watch-Dog-Timer with 8-bit pre-scaler (one-time-enabled). • SPI Master/Slave communication interface. • Two-channel Programmable Counter Array (PCA). • 10-bit, 8-channel Analog-to-Digital Converter (ADC). • Simple internal RC oscillator and external crystal clock. • Power control: idle mode (all interrupt can wake up IDLE mode), power-down mode (external interrupt can wake up Power-Down mode), and slow down mode. • Power down mode can be woken-up by PCA_pin, RXD_pin, T0/T1 pin, and external interrupts (INT0, INT1). • 44/40/36 programmable I/O ports are available. • Programmable clock output Function. T0 outputs the clock on P3.4, T1 outputs the clock on P3.5, BRT outputs the clock on P1.0. • External low-voltage detector function (P4.6, the EA pin at the pin location of standard 8051). • Five package types: LQFP-44, LQFP-48, PDIP-40, PLCC-44, QFN-40.
Application Scenarios
The STC12C5A16S2 microcontroller is suitable for various applications, including but not limited to: • Industrial automation • Consumer electronics • Internet of Things (IoT) devices • Robotics • Home appliances • Automotive electronics
Comparison
Advantages• Enhanced architecture for faster execution of instructions. • Support for In-System-Programming (ISP) and In-Application-Programming (IAP). • Fully compatible instruction set with the industrial-standard 80C51 series microcontroller. • Additional I/O ports, interrupt structure, ADC, UARTs, on-chip crystal oscillator, PCA and PWM, SPI, and a one-time enabled Watchdog Timer.
Disadvantages• Limited maximum external RAM addressability.
