Z8 CMOS OTP Microcontrollers

PS009201-0301

Programming Specification

6

8. Apply one clock pulse to XIN.

9. Force the Port 2 pins with F0h.

10. Apply one clock pulse to XIN.

11. Force the Port 2 pins with 0Fh.

12. Apply one clock pulse to XIN.

13. Force the Port 2 pins with 00h.

14. Apply one clock pulse to XIN.

15. Force the Port 2 pins with F1h.

16. Apply one clock pulse to XIN.

17. Force the Port 2 pins with 00h.

18. Apply one clock pulse to XIN.

19. The part is now in EPROM mode. The only way to exit EPROM mode is to

perform a POR.

All signals must be stable before the XIN (CE) pin is pulsed High and can-

not change until XIN (CE) pin is in a VIL state. The signal should be stable

for a minimum of 1µsec.
