File / buffer data
Device (D3 ~ D0)
Checksum
- It is calculated from the Buffer of the programmer.
- Address range is the same as device address.
- Calculate mathod is the same as normal EPROM devices (ex:27C128, 256 etc)
Programming control
- OSC1 & RESETB control OTP device, so you must count OSC1 clocks in every state.
- K ports control the internal state of the OTP device(ex: Read, Write...).
- D5~D0 ports are NMOS open drain I/O in EPROM mode.
It must be pulled up by resistors (about 4.7~ 47K ohm).
- The frequency rate of the OSC1 clock is 10KHz ~ 500KHz.
You can hold OSC1 HIGH or LOW state when you need.
