HN27C256FP

The HN27C256FP is a 32768-word by 8bit one time electrically programmable ROM. Initially ,all bits of the HV27C256FP are in the "1"state (output high).Data is introduced by selectively programming "o"into the desired bit locations.This device is packaged in a 28 pin plastic flat package(sop).Therefore,this device is packaged in a 28 pin plastic flat package(SOP).Therefore,this device cannot be re-written.

Features of the it are:(1)low power dissipation:40mW/MHz max.(Active Mode)110W max(standby mode); (2)access time:250ns max.(HN27C256FP.25T);300ns max.(HN27C256FP.30T); (3)static:no clocks required.

The absolute maximum ratings of the HN27C256FP can be summarized as:(1)operating temperature range:0~70; (2)storage temperature range:-55~125; (3)storage temperature range under bias:-10~80; (4)all input and output voltage:-0.6*~7V; (5)voltage on pin 24(A9)*1:-0.6*~13.5V; (6)Vpp Voltage:-0.6~14V; (7)Vcc Voltage:-0.6~7V.If you want to know more information such as the electrical characteristics, please download the datasheet in www.seekic.com or www.chinaicmart.com.
