STC12C5410AD STC12C5410AD series and STC12C2052AD series MCU are single clock/machine cycle (1T) MCUs produced by Hongjing Technology. They are a new generation of 8051 MCUs with high speed/low power consumption/super strong anti-interference. The instruction code is fully compatible with the traditional 8051, but the speed is 8-12 times faster. The internal integrated MAX810 dedicated reset circuit. 4-channel PWM, 8-channel high-speed 10-bit A/D conversion, for motor control, strong interference occasions. The STC12C2052AD series only has 2-channel PWM, 8-channel high-speed 8-bit A/D conversion. 1. Enhanced 8051 CPU, 1T, single clock/machine cycle, instruction code is fully compatible with traditional 8051 2. Operating voltage: STC12C5410AD series operating voltage: 5.5V - 3.5V (5V MCU) / 3.8V - 2.2V (3V MCU) STC12C2052AD series operating voltage: 5.5V - 3.5V (5V MCU) / 3.8V - 2.2V (3V MCU) 3. Operating frequency range: 0 - 35 MHz, equivalent to 0 ~ 420MHz of ordinary 8051 4. User application space 1K / 2K / 4K / 6K / 8K / 10K / 12K bytes...... 5. On-chip integrated 512 bytes RAM (STC12C5410AD series), STC12C2052AD series microcontrollers have 256 bytes of RAM 6. General I/O ports (27/23/15), after reset: Quasi-bidirectional port/weak pull-up (common 8051 traditional I/O port) can be set to four modes: Quasi-bidirectional port/weak pull-up, push-pull/strong pull-up, input only/high impedance, open drain Each I/O port can drive up to 20mA, but the maximum of the whole chip shall not exceed 55mA 7. ISP (In-System Programmable)/IAP (In-Application Programmable), no special programmer or emulator is required User programs can be downloaded directly through the serial port (P3.0/P3.1), and a chip can be completed in a few seconds 8. EEPROM function 9. Watchdog 10. Internally integrated MAX810 dedicated reset circuit (external reset circuit can be saved when the external crystal is below 12M) 11. Clock source: external high-precision crystal/clock, internal R/C When downloading the user program, the user can choose to use the internal R/C oscillator or the external crystal/clock. The internal R/C oscillator frequency at room temperature is: 5.2MHz ~ 6.8MHz. When the accuracy requirement is not high, the internal clock can be used, but due to manufacturing errors and temperature drift, it should be considered to be 4MHz ~ 8MHz. 12. A total of 6 16-bit timers/counters, two dedicated 16-bit timers T0 and T1 plus the PCA module can realize 4 more 16-bit timers, STC12C2052AD series has only two PCAs 13. 2 external interrupts, falling edge interrupts or low-level trigger interrupts, Power Down mode can be awakened by external interrupts 14. PWM (4 channels) / PCA (Programmable Counter Array, 4 channels), 5410 series has 4 channels, 2052 series has only 2 channels--- Can also be used as 4-channel D/A--- Can also be used to realize 4 more timers--- It can also be used to implement 4 more external interrupts (rising edge interrupt/falling edge interrupt can be supported separately or simultaneously) 15. A/D conversion, 10-bit precision ADC, 8 channels in total. STC12C2052AD series has only 8-bit precision16. Universal full-duplex asynchronous serial port (UART). Since STC12 series is a high-speed 8051, timer software can also be used to implement multiple serial ports17. SPI synchronous communication port, master mode / slave mode18. Operating temperature range: 0 - 75℃ / -40 - +85℃ 19. Package: LQFP-32, SOP-32/28/20, SKDIP-28, PDIP-20, TSSOP-20 (ultra-small package 6.4mm × 6.4mm, order) LQFP/SOP32 has 27 I/O ports, SOP28/SKDIP28 has 23 I/O ports, SOP20/TSSOP20/PDIP20 has 15 I/O ports. When the I/O ports are not enough, 2 to 3 ordinary I/O ports can be used The port line can be connected to 74HC164/165/595 (all can be cascaded) to expand the I/O port, and A/D can be used for key scanning to save I/O ports, or dual CPU, three-line communication, and an additional serial port.
