Ordering number : EN4430C CMOS LSI 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 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.
