It requires only one 5V power supply in normal read mode operation. Any word can be accessed in less than 45 ns, eliminating the need for speed reducing WAIT states. The by-16 organization make this part ideal for high-performance 16- and 32-bit microprocessor systems. In read mode, the AT27C516 typically consumes 15 mA. Standby mode supply current is typically less than 10 µA.

The device features two-line control (CE, OE) to eliminate bus contention in high-speed systems. With 32K word storage capability, the AT27C516 allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media. Atmel’s 27C516 have additional features to ensure high quality and efficient production use. The Rapid™ Programming Algorithm reduces the time required to program the part and guarantees reliable programming. Programming time is typically only 50 µs/word. The Integrated Product Identification Code electronically identifies the device and manufacturer. This feature is used by industry standard programming equipment to select the proper programming algorithms and voltages. Block Diagram 2 AT27C516 System Considerations Switching between active and standby conditions via the Chip Enable pin may produce transient voltage excursions. Unless accommodated by the system design, these transients may exceed data sheet limits, resulting in device non-conformance. At a minimum, 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 CC and Ground terminals of the device, as 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 VCC and Ground terminals. This capacitor should be positioned as close as possible to the point where the power supply is connected to the array.

The address is set to the first location. VCC is raised to 6.5V and VPP is raised to 13.0V. Each address is first programmed with one 50 µs PGM pulse without verification. Then a verification / reprogramming loop is executed for each address. In the event a word fails to pass verification, up to 10 successive 50 µs pulses are applied with a verification after each pulse. If the word fails to verify after 10 pulses have been applied, the part is considered failed. After the word verifies properly, the next address is selected until all have been checked. VPP is then lowered to 5.0V and VCC to 5.0V. All words are read again and compared with the original data to determine if the device passes or fails. 9 Ordering Information tACC (ns) ICC (mA) Active Standby Ordering Code Package 30 0.1 AT27C516-45JC AT27C516-45VC 44J 40V Commercial (0°C to 70°C) 30 0.1 AT27C516-45JI AT27C516-45VI 44J 40V Industrial (-40°C to 85°C) 30 0.1 AT27C516-55JC AT27C516-55VC 44J 40V Commercial (0°C to 70°C) 30 0.1 AT27C516-55JI AT27C516-55VI 44J 40V Industrial (-40°C to 85°C) 30 0.1 AT27C516-70JC AT27C516-70VC 44J 40V Commercial (0°C to 70°C) 30 0.1 AT27C516-70JI AT27C516-70VI 44J 40V Industrial (-40°C to 85°C) 30 0.1 AT27C516-85JC AT27C516-85VC 44J 40V Commercial (0°C to 70°C) 30 0.1 AT27C516-85JI AT27C516-85VI 44J 40V Industrial (-40°C to 85°C) 30 0.1 AT27C516-10JC AT27C516-10VC 44J 40V Commercial (0°C to 70°C) 30 0.1 AT27C516-10JI AT27C516-10VI 44J 40V Industrial (-40°C to 85°C) 45 55 70 85 100 Package Type 44J 44-Lead, Plastic J-Leaded Chip Carrier (PLCC) 40V 40-Lead, Plastic Thin Small Outline Package (VSOP) (10mm x 14mm) 10 AT27C516 Operation Range AT27C516 Packaging Information 44J, 44-Lead, Plastic J-Leaded Chip Carrier (PLCC) Dimensions in Inches and (Millimeters) JEDEC STANDARD MS-018 AC 40V, 40-Lead, Plastic Thin Small Outline Package (TSOP) Dimensions in Millimeters and (Inches) JEDEC OUTLINE MO-142 CA .045(1.14) X 45° PIN NO. 1 IDENTIFY .045(1.14) X 30° - 45° .012(.305) .008(.203) .630(16.0) .590(15.0) .656(16.7) SQ .650(16.5) .032(.813) .026(.660) .695(17.7) SQ .685(17.4) .050(1.27) TYP .500(12.7) REF SQ .021(.533) .013(.330) .043(1.09) .020(.508) .120(3.05) .090(2.29) .180(4.57) .165(4.19) .022(.559) X 45° MAX (3X) 11 Atmel Headquarters Atmel Operations Corporate Headquarters Atmel Colorado Springs 2325 Orchard Parkway San Jose, CA 95131 TEL (408) 441-0311 FAX (408) 487-2600 Europe 1150 E.
