27128A

27128A 128K (16K x 8) PRODUCTION AND UV ERASABLE PROMs Fast 150 nsec Access Time - HMOS* 11-E Technology Low Power - 100 mA Maximum Active - 40 mA Maximum Standby intellgent Identifier™ Mode - Automated Programming Operations ± 10% Vee Tolerance Available Available in 28-Pin Cerdip Package (See Packaging Spec, Order #231369) The Intel 27128A is a 5V only, 131, 072-bit ultraviolet erasable and electrically programmable read-only memo­ ry (EPROM). The 27128A is fabricated with Intel's HMOS* 11-E technology which significantly reduces die size and greatly improves the device's performance, reliability and manufacturability. The 27128A is currently available in the CERDIP package providing flexibility in prototyping and R&D environ­ ments where reprogrammability is required. The 27128A is available in fast access times including 15 0 ns ( 27128A-1).This ensures compatibility with high­ performance microprocessors, such as Intel's 8 MHz 8 0 186 allowing full speed operation without the addition of WAIT states. The 27128A is also directly compatible with the 12 MHz 8 0 5 1 family. *HMOS is a patented process of Intel Corporation. Vcco<>--" GND O<>---<.�.
