Features
AI Translation
- 2048-byte on-chip RAM data memory
- High speed: 1 clock/machine cycle, enhanced 8051 core, 7~12x faster than standard 8051, also 20% faster than STC's early 1T series MCUs (e.g. STC12/11/10 series)
- Wide voltage range: 5.5~3.8V, 2.4~3.6V (STC15L2K60S2 series)
- Low-power design: slow-speed mode, idle mode, power-down mode (wake-up via external interrupt or internal power-down wake-up timer)
- No external reset required; 8 selectable reset threshold voltages during ISP programming; built-in high-reliability reset circuit
- No external crystal required; internal clock selectable from 5MHz~35MHz (equivalent to standard 8051: 60~420MHz); internal high-precision R/C oscillator (±0.3%); ±1% temperature drift (-40℃~+85℃); ±0.6% temperature drift at room temperature (-20℃~+65℃)
- Power-down wake-up sources: INT0/INT1 (rising/falling edge), INT2/INT3/INT4 (falling edge); CCP0/CCP1/CCP2/T0/T1/T2 pins; dedicated internal power-down wake-up timer
- 8/16/24/32/40/48/56/60/61K bytes on-chip Flash program memory, 100,000+ erase/write cycles
- Large on-chip EEPROM, 100,000+ erase/write cycles
- ISP/IAP, in-system programmable/in-application programmable, no programmer/emulator required
- High-speed ADC: 8-channel 10-bit, up to 300,000 samples/sec; 3 PWM channels also usable as 3 D/A outputs
- 3-channel capture/compare unit (CCP/PCA/PWM), also configurable as 3 D/A outputs, 3 timers, or 3 external interrupts (rising/falling edge)
- 6 timers: two 16-bit auto-reload timers T0 and T1 compatible with standard 8051; new 16-bit timer T2 with clock output capability; 3 CCP/PCA channels provide 3 additional timers
- Programmable clock output (clock division output from internal system clock or external pin input): T0 outputs clock on P3.5; T1 outputs clock on P3.4; T2 outputs clock on P3.0; all 3 timer/counter clock outputs support 1~65536 division; internal master clock output on P5.4/MCLKO (STC15 series 8-pin MCUs output master clock on P3.4/MCLKO)
- Dual high-speed UART: two fully independent high-speed async serial ports, time-division multiplexing supports up to 5 serial port groups
- Hardware watchdog timer (WDT)
- SPI high-speed synchronous serial interface
- Advanced instruction set architecture, compatible with standard 8051 instruction set, hardware multiply/divide instructions
- General-purpose I/O (42/38/30/26 pins): quasi-bidirectional/weak pull-up after reset (standard 8051 I/O mode); four configurable modes: quasi-bidirectional/weak pull-up, push-pull/strong pull-up, input-only/high-impedance, open-drain; each I/O pin drive capability up to |20mA, with total chip current not exceeding 120mA
- If I/O pins are insufficient, use 3 I/O lines to interface 74HC595 for expansion; multiple chips can be cascaded for dozens of additional I/O pins; ADC-based key scanning also saves I/O pins
- No external crystal required; integrated high-precision R/C oscillator (±0.3%); ±1% temperature drift (-40℃~+85℃); ±0.6% temperature drift at room temperature (-20℃~+65℃)
- No external reset required; integrated high-reliability reset circuit; 8 selectable reset threshold voltages during ISP programming; external reset circuit remains optional
- Large on-chip 2048-byte SRAM
- Unbreakable encryption — Macrocrystal 8th-generation encryption technology
- Exceptional noise immunity:
- High ESD protection — system-level ESD withstand up to 20,000V
- Passes 4kV EFT (fast transient burst) test
- Wide voltage range — immune to power supply fluctuation
- Wide temperature range: -40℃~+85℃
- Significantly reduced EMI: configurable internal clock, 1 clock/machine cycle, supports low-frequency clock operation
- Ultra-low power consumption:
- Power-down mode: wake-up current <0.1uA
- Idle mode: typical current <1mA
- Normal operating mode: 4mA~6mA
- Power-down mode wake-up via external interrupt or dedicated internal power-down wake-up timer; ideal for battery-powered systems such as water meters, gas meters, and portable devices
- In-system emulation and in-system programming; no dedicated programmer or emulator required; supports remote firmware upgrade
