Microchip Technology presents the AT28HC256-12LM, a 262,144-bit (32K x 8) Electrically Erasable Programmable Read-Only Memory. This CMOS device offers a 120ns access time and supports asynchronous operation. The AT28HC256 series provides automatic write capabilities with data polling and toggle bit features for efficient data management. Designed for robust performance, it operates within a -55°C to +125°C temperature range. The component is housed in a 32-terminal ceramic chip carrier (CQCC32) with surface-mount configuration. Its memory organization facilitates a 32K x 8 structure, and it supports parallel data transfer. Endurance is rated at 10,000 write cycles. Applications for this memory component span industrial control, aerospace, and defense systems.
