M2732A NMOS 32K (4K x 8) UV EPROM FAST ACCESS TIME: 200ns EXTENDED TEMPERATURE RANGE SINGLE 5V SUPPLY VOLTAGE LOW STANDBY CURRENT: 35mA max INPUTS and OUTPUTS TTL COMPATIBLE DURING READ and PROGRAM COMPLETELY STATIC 24 1 FDIP24W (F) DESCRIPTION The M2732A is a 32,768 bit UV erasable and electrically programmable memory EPROM. It is organized as 4,096 words by 8 bits. The M2732A with its single 5V power supply and with an access time of 200 ns, is ideal suited for applications where fast turn around and pattern experimentation one important requirements. The M2732A is honsed in a 24 pin Window Ceramic Frit-Seal Dual-in-Line package. The transparent lid allows the user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can be then written to the clerice by following the programming procedure. Figure 1. Logic Diagram VCC 12 A0-A11 8 Q0-Q7 E M2732A Table 1.
