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

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.
