11.2.2 Socket Adapter Pin Assignments and Memory Map
The H8/3257, H8/3256, H8/325, H8/323, and H8/322 can be programmed with a general-purpose
PROM writer. Since the microcontroller package has 64 pins instead of 28 or 32 pins, a socket
adapter is necessary. Table 11-3 lists recommended socket adapters. Figures 11-2 and 11-3 show the
socket adapter pin assignments by giving the correspondence between microcontroller pins and
HN27C101 or HN27C256 pin functions.
Figures 11-4 to 11-8 show memory maps in PROM mode. Since the H8/3257 has 60 Kbytes of on-
chip PROM, the address range should be specified as H’0000 to H’EFFF. H’FF data should be
specified for unused address areas.
The H8/3256 has only 48 Kbytes of PROM. The H8/325 has only 32 Kbytes. The H8/323 has only
16 Kbytes. The H8/322 has only 8 Kbytes. When programming these microcontrollers with a
PROM writer, specify an address range of H’0000 to H’BFFF for the H8/3256, H’0000 to H’7FFF
for the H8/325, H’0000 to H’3FFF for the H8/323, or H’0000 to H’1FFF for the H8/322. Specify
H’FF data for addresses equal to or greater than H’C000 (H8/3256), H’8000 (H8/325), H’4000
(H8/323) or H’2000 (H8/322). Also specify H’FF data for unused address areas. If these areas are
programmed by mistake, it may become impossible to write or verify PROM data. Be particularly
careful with microcontrollers in plastic packages, in which the PROM cannot be reprogrammed.
