8 bits) Pseudo-SRAM
Overview
The LC33832 series is composed of pseudo static RAM
that operates on a single 5 V power supply and is
organized as 32768 words
脳
8 bits. By using memory
cells each composed of a single transistor and capacitor,
together with peripheral CMOS circuitry, this series
achieves ease of use with high density, high speed, and
low power dissipation. The LC33832 series can easily
accomplish auto-refresh and self-refresh by means of
OE/RFSH input. As with asynchronous static RAM, WE
input uses a system for incorporating input data at the WE
rise, thereby facilitating interfacing with a microcomputer.
The LC33832 series features pin compatibility with 256 K
static RAM (the LC36256A series), and available
packages are the standard 28-pin DIP with widths of 600
mil or 300 mil, and the SOP with a width of 450 mil.
CE-only refresh can be accomplished by selecting address
256 (A0 to A7) within 4 ms.
