STK88C2441 - Adpcm Voice Controller

Description

8-bit I/O pins for port 1 with wake-up interrupt I/O 8-bit I/O pins for port 2.

8-bit I/O pins for port 3.

PC0-PC7 will changed to BANK0BANK7 output if bank number is less than $F0 or /DIROM=0.

Features

  • Operating voltage : 2.5V - 5.5V.
  • Maximum CPU operating frequency : 4,194,304Hz at 2.7V.
  • Provide X’tal or RC oscillator. Both can run at high speed or slow speed(low power). RC oscillator can detect internal or external resister automatically.
  • Support 4M bytes program and data ROM. 256K bytes of them are built-in.
  • Built in 128 bytes RAM.
  • I/O port. 24 I/O pins. 8 of 24 pins with wake up function.
  • Six 8-bit timers.
  • Four channels for voice or melody pr.
