Part Number : HG62E
Function : CMOS Gate Array
Package : QFP-64 Pin Type
Maker : Hitachi , Renesas Electronics
Pinouts : 
Description :
The HG62E series is a master slice CMOS gate array of which the gate length is 1um and user 2-layer metal interconnect technology.
This series has twelve master chips with high gate count/pads from 770/68 to 24,000/272.
These chips can replace not only CMOS logics but also TTL logics due to the high speed of 0.7 ns typ and compatibility of input and output buffers at TTL/CMOS level.
Features :
1. Auto-diagnoisis
2. Fast Operation
3. Low Power dissiaption
4. Powerful design support
