1-Megabit (128K x 8) OTP EPROM

Description

The AT27C010(L) is a l ow- pow er , h igh -per forma nc e 1,04 8,5 76- bi t o ne-ti me pr og rammable read only memory (OTP EPROM) organized as 128K by 8 bits. They require only one 5V power supply in normal read mo de opera tion. An y byte can be ac ces sed in less than 45 ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems.

Two power versions are o ffered . In r ead mod e, the AT27C010 typica lly c onsu mes 25 mA while the AT27C010L requires only 8 mA. Standby mode supply current for both parts is typically less than 10 µA.

System Considerations

Switching between active and standby conditions via the Chip Enable pin may produ ce tra ns ien t vo ltag e ex cu rs i ons . Unless accommodated by the system design, these transients may exceed data sheet limits, resulting in device non-conforman ce. At a mini mum, a 0.1 µF high frequency, low inherent inductance, ceramic capacitor should be utilized for each device. This capacitor should be connected between the V close to the device as possible. Additionally, to stabilize the supply voltage level on printed circuit boards with large EPROM arrays, a 4.7 µF bulk electrolytic capacitor should be utilized, again connected between the V terminals. This capacitor should be positioned as close as possible to the point where the power supply is connected to the array.
