STC12LE2052

STC12LE2052 is a single-chip microcontroller based on a high performance 1T architecture 8051 CPU, which is produced by STC MCU Limited. With the enhanced kernel, STC12LE2052 executes instructions in 1~6 clock cycles (about 8~12 times the rate of a standard 8051 device), and has a fully compatible instruction set with industrial-standard 8051 series microcontroller. In-System-Programming (ISP) and In-Application-Programming (IAP) support the users to upgrade the program and data in system. ISP allows the user to download new code without removing the microcontroller from the actual end product; IAP means that the device can write non-valatile data in Flash memory while the application program is running. The STC12LE2052 retains all features of the standard 80C51. In addition, theSTC12LE2052 has a 9-sources, 4-priority-level interrupt structure, 10-bit ADC(100 thousands times per second), on-chip crystal oscillator, MAX810 special reset circuit, 4-channel PCA and PWM, SPI, a one-time enabled Watchdog Timer and so on.
