LC33832P, S, M, PL, SL, ML-70/80/10
256 K (32768 words × 8 bits) Pseudo-SRAM
Overview
The LC33832 series is composed of pseudo static RAM t h a t 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, t o g e t h e r with peripheral CMOS circuitry, this series achieves ease of use with high density, high speed, and low power dissipation. The LC33832 series can easily a c c o m p l i s h 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 s t a t i c 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.
