11 / 44 page  11 MB89628R/629R/P629 s PROGRAMMING TO THE EPROM ON THE MB89P629 The MB89P629 is an OTPROM version of the MB89628R and MB89629R. 1. Features • 16-Kbyte PROM on chip • Options can be set using the EPROM programmer. • Equivalency to the MBM27C256A in EPROM mode (when programmed with the EPROM programmer) 2. Memory Space Memory space in EPROM mode, option area is diagrammed below. 3. Programming to the EPROM In EPROM mode, the MB89P629 functions equivalent to the MBM27C256A. This allows the PROM to be programmed with a general-purpose EPROM programmer (the electronic signature mode cannot be used) by using the dedicated socket adapter. • Programming procedure (1) Set the EPROM programmer to the MBM27C256A. (2) Load program data into the EPROM programmer at 0000H to 7FFFH (note that addresses 8000H to FFFFH while operating as a single chip assign to 0000H to 7FFFH in EPROM mode. For information about each corresponding option, see “7. Setting OTPROM Options.”) (3) Program to 0000H to 7FFFH with the EPROM programmer. Program area (EPROM) 32 KB 7FFFH 0000H Option area Option area 0007H 0000H Address 0080H 0100H 0200H 8000H Single chip I/O RAM Register PROM 32 KB Not available 1080H 8007H FFFFH EPROM mode (Corresponding addresses on the EPROM programmer) |
