Product>>8051 MicroController>>STC15F204EA series


Features:

 

  • Enhanced 80C51 Central Processing Unit, faster 6~7 times than the rate of a traditional 8051.
  • Operating voltage range: 3.8 ~ 5.5V or 2.4V ~ 3.6V (STC15L204EA series)
  • Operating frequency range: 5MHz ~ 35MHz, is equivalent to standard 8051: 60MHz ~ 420MHz
  • A high-precision internal RC oscillator with temperature drifting ±1% (-400C~+850C)
  • Internal RC oscillator with adjustable frequency to 5.5296MHz /11.0592MHz /22.1184MHz /33.1776MHz
  • On-chip 256 bytes RAM and 1K~6K bytes code flash with flexible ISP/IAP capability
  • EEPROM function
  • Code protection for flash memory access.
  • Two 16-bit timers/counters — Timer 0 / Timer 1 with mode 0 (16-bit auto-reload mode), mode 1 (16-bit timer mode) and mode 2 (8-bit auto-reload mode).
  • Simulate UART can be realized by P3.0,P3.1 and Timers
  • 8-channel, 10-bit ADC associated interrupt, speed up to 300 thousands times every second
  • 9 interrupt sources
  • One 15 bits Watch-Dog-Timer with 8-bit pre-scalar (one-time-enabled)
  • Three power management modes: idle mode, slow down mode and power-down mode.
  • Power down mode can be woken-up by external INTx pin (INT0/P3.2, INT1/P3.3, INT2 , INT3, INT4 ).
  • Excellent noise immunity, very low power consumption
  • Support 2-wire serial flash programming interface.(GND/P3.0/P3.1/VCC)
  • Programmable clock output Function. T0 output the clock on P3.5, T1 output clock on P3.4.
  • 26 configurable I/O ports are available and default to quasi-bidirectional after reset. All ports may be independently configured to one of four modes : quasi-bidirectional, push-pull output, input-only or opendrain output.
  • The drive capability of each port is up to 20 mA. But recommend the whole chip's should be less than 90 mA.
  • Package type: SOP-28,SKDIP-28 SOP20, PDIP20
  • All products are baked 8 hours in high-temperature 175°C after be packaged ,Manufacture guarantee good quality.
  • In Keil C development environment, select the Intel 8052 to compiling and only contain < reg51.h >
