.. IC89E54/58/64 8-BITS SINGLE MICROCONTROLLER with 16/32/64-Kbytes of FLASH, 256 byte +512 byte RAM 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 : 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 patible 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 twolevel priority, Power off flag, Low EMI mode, power down mode is waken up from interrupt level trigger 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 patible 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 - 44-pin PQFP 16K/32K/64K Byte Flash Memory with fast-pulse programming algorithm 36 I/O pins(above 44-pin package only) 8 interrupts vectors (above 44-pin package only) Low EMI mode - - - - - - T2/P1.0 T2EX/P1.1 P1.2 P1.3 P1.4 P1.5 P1.6 P1.7 RST Rx D/P3.0 Tx D/P3.1 INT0/P3.2 INT1/P3.3 T0/P3.4 T1/P3.5 WR/P3.6 RD/P3.7 XTAL2 XTAL1 VSS 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 VCC P0.0/AD0 P0.1/AD1 P0.2/AD2 P0.3/AD3 P0.4/AD4 P0.5/AD5 P0.6/AD6 P0.7/AD7 EA/VPP ALE/PROG PSEN P2.7/A15 P2.6/A14 P2.5/A13 P2.4/A12 P2.3/A11 P2.2/A10 P2.1/A9 P2.0/A8 - - - - Figure 1.
