HN27C256H

The HN27C256H is designed as one kind of 256-kilobit ultraviolet erasable and one-time programmable electrically programmable read only memory organized as 32768 X 8-bits.Its features fast address access times and low power dissipation.This combination makes it suitable for high speed microcomputer systems.The HN27C256H also offers high speed programming.And it is offered in JEDEC-standard byte-wide EPROM pinouts in 28-pin ceramic and plastic DIP and 28-lead plastic SOP packages.The ceramic DIP package is erasable by exposure to Ultraviolet light.The plastic DIP and SOP package devices are one-time programmable and once programmed,can not be rewritten.

Features of the HN27C256H can be summarized as:(1)supply voltage:-0.6 to +7.0 V;(2)programming voltage:-0.6 to +13.5 V;(3)all input and output voltage:-0.6 to +7.0 V;(4)input voltage:-0.6 to +13.5 V;(5)operating temperature range:0 to +70 ;(6)storage temperature range:-65 to +125 and -55 to +125 ;(7)storage temperature under bias:-10 to +80.If you want to know more information such as the electrical characteristics about this part, please download the datasheet in www.seekic.com and www.chinaicmart.com .
