1. Operating voltage: 2.5V-5.5V
2. Operating frequency range: 5MHz ~ 35MHz, equivalent to 60MHz ~ 420MHz of ordinary 8051
3. Low-power design: low-speed mode, idle mode, power-down mode/stop mode.
4. Operating temperature range: -40 ~ +85°C (industrial grade) / 0 ~ 75°C (commercial grade)
5. Package: SOP-8, DIP-8, DFN-8
6. Development environment: In the Keil C development environment, select Intel 8052 to compile

Features:

• 4K word byte on-chip Flash program memory, erase and write times 10 million times more
• 128-byte SRAM XRAM (xdata)
• On-chip EEPROM function, endurance more than 100,000
• ISP / IAP, programmable system / application programmable, without a programming device / emulator
• Highly reliable internal Reset, 16-level reset threshold voltage can be selected during ISP programming, which can completely eliminate the external reset circuit.
• Internal high-precision R/C clock (±0.3%), ± 1% temperature drift (-40℃~+85℃), normal temperature drift ±0.6% (-20℃~+65℃), the internal clock can be set from 5MHz~35MHz (5.5296MHz / 11.0592MHz / 22.1184) during ISP programming MHz / 33.1776MHz).
• No need for external crystal oscillator and external reset, and it can also output clock and low-level reset signal.
• Supports RS485 download
• Serial port function can be created by [P3.0/INT4, P3.1] combined with timer to support program encryption and transmission.
• 2 timers/counters - T0 (compatible with ordinary 8051 timers)/T2, and can realize programmable clock output, and pin MCLKO can divide the internal main clock to external frequency output (÷1 or ÷2 or ÷4).
• Timer that can wake up power-down mode/stop mode: there is an internal low-power power-down wake-up dedicated timer
• The resources that can wake up the power-down mode/stop mode are: INT0/P3.2, INT1/P3.3 (INT0/INT1 rising edge and falling edge interrupts are both), INT2 /P3.4, INT3/P3.5, INT4 /P3.0 (INT2 /INT3 /INT4 can only be interrupted on the falling edge); pin T0/T2 (falling edge, no interrupt is generated, provided that the corresponding timer interrupt has been enabled before entering the power-down mode/stop mode) ; Internal low-power consumption power-down wake-up dedicated timer.
• Programmable clock output function (clock frequency division output for internal system clock or external pin clock input):
• Since the external output speed of the STC15 series 5V microcontroller I/O port does not exceed 13.5MHz, the 5V microcontroller’s external output speed The fastest programmable clock output speed does not exceed 13.5MHz. The fastest external output speed of the 3.3V microcontroller I/O port does not exceed 8MHz, so the fastest external programmable clock output speed of the 3.3V microcontroller does not exceed 8MHz.
