same way as any other commercial 27256-type EPROM using a standard PROM programmer and an 80-to-
28-pin socket adapter. Recommended PROM programmers and socket adapters are listed in table 31.
Since an HMCS400-series instruction is ten bits long, the HMCS400-series MCU has a built-in conversion
circuit to enable the use of a general-purpose PROM programmer. As shown in figure 90, this circuit splits
each instruction into five lower bits and five upper bits that are read from or written to consecutive
addresses. This means that if, for example, 16 kwords of built-in PROM are to be programmed by a
general-purpose PROM programmer, a 32-kbyte address space ($0000–$7FFF) must be specified.

Warnings
1. Always specify addresses $0000 to $7FFF when programming with a PROM programmer. If address
$8000 or higher is accessed, the PROM may not be programmed or verified correctly. Set all data in
unused addresses to $FF.
Note that the plastic-package version cannot be erased and reprogrammed.
2. Make sure that the PROM programmer, socket adapter, and LSI are aligned correctly (their pin 1
positions match), otherwise overcurrents may damage the LSI. Before starting programming, make
sure that the LSI is firmly fixed in the socket adapter and the socket adapter is firmly fixed onto the
programmer.
3. PROM programmers have two voltages (V
PP
): 12.5 V and 21 V. Remember that Hitachi devices require
a V
PP
of 12.5 V—the 21-V setting will damage them. 12.5 V is the Intel 27256 setting.
Programming and Verification
The built-in PROM of the MCU can be programmed at high speed without risk of voltage stress or damage
to data reliability.
