Overview
Ordering number : EN*5239A CMOS LSI LE28F4001M, T, R-15/20 4 MEG (524288 words × 8 bits) Flash Memory Preliminary Overview The LE28F4001 Series ICs are 524288-word × 8-bit flash memory products that support on-board reprogramming and feature 5 V single-voltage power supply operation.
CMOS peripheral circuits were adopted for high speed, low power, and ease of use.
These products support a sector (256 bytes) erase function for fast data rewriting.
Package Dimensions unit: mm 3205-SOP32 [LE28F4001M] Features • Fabricated in a highly reliable 2-layer polysilicon CMOS flash EEPROM process.
• Read and write operation from a 5 V single-voltage power supply • Sector erase function: 256 bytes per sector • Fast access time: 150/200 ns • Low power — Operating current (read): 25 mA (maximum) — Standby current: 20 µA (maximum) • Highly reliable read and write operations — Sector write cycles: 104 cycles — Data retention time: 10 years • Address and data latches • Self-timer erase and programmi...
