AP160 AMICC [AMIC Technology], AP160 Datasheet - Page 14

• Manufacturer Part Number: AP160
• Description: 8-BIT MICROCONTROLLER WITH 8KB OTP
• Manufacturer: AMICC [AMIC Technology]

EPROM PROGRAMMING MODE
The setup for programming and verification on-chip OPT EPROM of AP160 is shown in Figure 7 and Figure 8,
independently. The address of the EPROM location to be programmed is applied to ports 1 and 2. The code byte to be
programmed into that location and read verified data are applied to port 0. The programming, verifying, Write Lock bits and
read signature byte mode are selectable by the pins of RST, PSEN, ALE/PROG, P2.6, P2.7, P3.6 and P3.7, as shown in
table 8. The programming and verification waveform is shown in Figure 9. VCC must be rising to VCC1 during
programming.
