[STC micro™]

Hongjing STC90C51 series single chip microcomputer

Hongjing STC90C51 series solves the problem that the 89 series of all manufacturers in the world have been decrypted, and the software and hardware are fully compatible
Welcome to use the STC90xx series that cannot be decrypted by Hongjings latest seventh-generation encryption technology, no need to change software and hardware, and the pins are compatible with traditional 8051
Your support is a strong guarantee for mainland Chinas local forces to unify the global market

Reasons for choosing Hongjing STC90C51 series MCU:
★ It cannot be decrypted, and the software and hardware are fully compatible with global manufacturers
   The 89 series microcontrollers that have been decrypted can be directly replaced
★ Large capacity SRAM, up to 4.2K bytes SRAM
   High-speed 10-bit A/D, up to 250,000 times/second
★ Super anti-interference:
   1. High anti-static (ESD, the whole machine easily exceeds 20,000 volts)
   2. Easily pass 4KV fast pulse interference (EFT test)
   3. Wide voltage, not afraid of power supply jitter
   4. Wide temperature range, -40˚C ~ 85˚C
★ Three measures to reduce the external electromagnetic radiation of the single chip clock:
   --A strong guarantee for export to Europe and the United States
   1. Disable ALE output;
   2. If 6 clocks/machine cycle is selected, the external clock frequency can be reduced by half;
   3. The gain of the MCU clock oscillator can be set to 1/2 gain.
★ Ultra-low power consumption:
   1. Power-down mode: Typical power consumption <0.1μA
   2. Normal working mode: typical power consumption 4mA - 7mA
   3. Power-down mode can be woken up by external interrupt, suitable for battery
      Power supply systems, such as water meters, gas meters, portable devices, etc.
★ In-system programmable, no programmer, no emulator
★ Can send STC-ISP to download programmer, 10,000 pieces/person/day
