80C51 central processing unit.
The 8KFlash storage space is used to store user programs, ISP programs, and IAP data.
The ISP space defaults to 1 KB, and the remaining Flash storage space is 7 KB. It shares by the program space of 7 KB (maximum use) and the IAP data space of 2.5 KB (maximum usage).
There are 256 bytes of static RAM on the chip, and the chip can also expand RAM to 64K.
Provides three kinds of code security mechanisms for disabling MOVC instructions, data encryption, and program storage space locking.
Three 16-bit timers/counters, Timer 2 can be set to an up/down counter and programmed for clock output on port P1.0.
Eight interrupt sources; four priority interrupt function.
Dual DPTR registers are available for quick access to the data memory space.
15-bit watchdog timer with 8-bit one-time enable.
What can turn off the ALE output to reduce EMI?
There are two power control modes: idle mode and power-down mode. Any interrupt source can awaken idle mode. In a power-down way,
P3.2/P3.3/P4.2/P4.3 external interrupt wake-up.
Long-term focus on the design of encryption chip functions and software algorithm research, algorithm software implementation and hardware function implementation, system software development, and chip underlying driver design, accumulated in the field of MCU/CPLD/SPLD/PLD chip decryption technology Rich development experience.
