IC89E54中文资料8-BITS SINGLE MICROCONTROLLER with 16/32/64-Kbytes of FLASH, 256 byte +512 byte RAM数据手册ISSI规格书

描述 Description

GENERAL DESCRIPTION
IC89E54, IC89E58, IC89E64 are members of ICSI embedded microcontroller family. The IC89E54/58/64 uses the same powerful instruction set, has the same architecture, and is pin-to-pin compatible with standard 80C51 controller devices. They have IC89E54/58/64 all functions and some enhanced function is included. These enhanced functions include 512 bytes auxiliary memory, 36 I/O pins (44 pin package only), 8 interrupts (44 pin package only) with two level priority, Power off flag, Low EMI mode, power down mode is waken up from interrupt level trigger mode.FEATURES
• 80C52 based architecture
• 256 Byte RAM internal RAM and 512 Bytes auxiliary RAM available
• Three 16-bit Timer/Counters
• Full duplex serial channel
• Boolean processor
• Power Save Mode :
   1) Idle Mode
   2) Power Down Mode - waken up from interrupt level trigger mode
• Program memory lock
   – Lock bits (3)
• Four 8-bit I/O ports, 32 I/O lines
• Memory addressing capability
   – 64K Program Memory and 64K Data Memory
• CMOS and TTL compatible
• Maximum speed ranges at Vcc = 5V is 40 MHz and most instructions execute in 0.3 µs
• Packages available:
   – 40-pin DIP
   – 44-pin PLCC
