UPD445L-1 Description

The ~PD445L is a very low power 4,,096 bit (1024 words by 4 bits) static RAM fabricated with NEC's plementary MOS (CMOS) process, It has two chip enable inputs (CE1, I I ' CE2). Minimum standby current is drawn when CE1 is at a high level, while inhibiting all address and control line transitions or, unconditionally when CE2 is at a low level. This device ideally meets the low power requirements of battery operated...
