CXP402 Overview
The CXP402 is a CMOS 4-bit single chip microputer which consists of 4-bit CPU, ROM, RAM, 8-bit timer, 8-bit timer/counter, 18-bit time-base timer, LCD controller/driver, digital signal processor circuit for CD player, 1-bit DAC and the like.
CXP402 Key Features
- Instruction cycle 1.89µs for 16.93MHz oscillation
- ROM capacity 6144 × 8 bits
- RAM capacity 400 × 4 bits (Including stack and display area)
- LCD controller/driver (Enables to direct drive)
- 8-bit timer, 8-bit timer/event counter and 18-bit time-base timer are incorporated; they are independently controllable
- Arithmetic and logical operations between the entire RAM area, I/O area and the accumulator by means of the memory mappe
- Entire ROM area can be referred by the table lookup instruction. Digital Signal Processor (DSP) Block
- Playback mode supporting CAV (Constant Angular Velocity)
- Frame jitter free
- Allows relative rotational velocity readout
