A. 1.1.4 HM65256BLSP (5A)
The HM65256BLSP is a 32K-word x 8-bit pseudo-static RAM (PSRAM) which features low power consump-
tion (because CMOS peripheral circuits are used) and high speed and capacity (because a single transistor
memory cell is used). The pin diagram of the HM65256BLSP is provided in Figure A-8, and a block diagram
in Figure A-9.
