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.

NOTES:
1. Typical values are for TA= 25'C and nominal supply voltages.
2. This parameter is only sampled and is not 100% tested.
3. OE may be delayed up to tcE-toE after the falling edge of CE without impact on lcE·
