MSM6641E-XXGS-K数据手册OKI中文资料规格书

描述 Description

GENERAL DESCRIPTION
The MSM6641, powered by a single battery, is a 4-bit microcontroller fabricated in OKI’s low voltage CMOS technology. A remote-control output generator built into this device provides remote-control output.
The MSM6641 is best suited to remote-control applications.FEATURES
• Operating range
   Operating voltage : 1.5 V (MSM6641)
                             3.0 V (MSM6641E)
  Operating frequency : 1 MHz
  Operating temperature : –20 to +70°C
• Memory space
  ROM : 4096 words × 17 bits
  RAM : 64 words × 4 bits
• Minimum instruction execution time : 16 µs
• I/O port
   Input port : 2 ports x 4 bits
                   1 port x 1 bit
   Output port : 2 ports x 4 bits
                     1 port x 1 bit
• Remote-control output port : 1
  The remote-control output circuit consists of a carrier generator, a guide pulse and data pulse generator, and an output waveform controller. The remote control output can be provided by setting the control registers.
• Key-On Wake-Up function
  Oscillation can be stopped to turn off microcontroller operation. Application of predetermined input levels to the input ports turns on oscillation and microcontroller operation.
• Halt release timers : 4
                           Timer frequencies are selectable.
• Watchdog timers : 2
• Clock : 1 MHz ceralock resonator
• Power supply voltage : 1.5 V/3.0 V (mask option)
• Package:
  24-pin plastic SOP (SOP24-P-430-K) (Product name : MSM6641-¥¥GS-K, MSM6641E-xxGS-K) Chip
