STC12C5A56S2-35I-LQFP44 - Brand New STMicroelectronics IC Chips
-
Description
The STC12C5A56S2-35I-LQFP44 is a single-chip microcontroller produced by STC MCU Limited. It is based on a high-performance 1T architecture 80C51 CPU and offers enhanced features and performance compared to standard 8051 devices. The microcontroller supports In-System Programming (ISP) and In-Application Programming (IAP), allowing for easy program and data upgrades without removing the device from the end product. It retains all the features of the standard 80C51 and includes two extra I/O ports, a 10-bit ADC, two UARTs, on-chip crystal oscillator, a 2-channel PCA and PWM, SPI, and a one-time enabled Watchdog Timer.
Specifications and features
- Enhanced 80C51 Central Processing Unit with 1T per machine cycle
- Operating voltage range: 5.5V ~ 3.5V or 2.2V ~ 3.6V (STC12LE5A60S2)
- Operating frequency range: 0-35MHz
- 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
- Dual Data Pointer (DPTR) to speed up data movement
- Code protection for flash memory access
- Four 16-bit timer/counter, compatible with Timer0/Timer1 of standard 8051
- 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 bits 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 output the clock on P3.4, T1 output the clock on P3.5, BRT output the clock on P1.0
- External low-voltage detector function (P4.6, the EA pin at the pin location of the standard 8051)
- Five package types: LQFP-44, LQFP-48, PDIP-40, PLCC-44, QFN-40
Application Scenarios
The STC12C5A56S2-35I-LQFP44 microcontroller is suitable for a wide range of applications including industrial control systems, home automation, consumer electronics, and automotive electronics. Its features and capabilities make it versatile and ideal for various embedded systems.
