At V C C = 2.7V, any byte can be accessed in less than 90 ns. With a typical power draw of only 18 mW at 5 MHz and VCC = 3V, the AT27BV010 consumes less than one fifth the power of a standard 5V EPROM. Standby mode supply current is typically less than 1 µA at 3V. The AT27BV010 simplifies system design and stretches battery lifetime even further by eliminating the need for power supply regulation. The AT27BV010 is available in industry standard JEDECapproved one-time programmable (OTP) plastic PLCC, TSOP, and VSOP packages. All devices feature two-line control (CE, OE) to give designers the flexibility to prevent bus contention. The AT27BV010 operating with VCC at 3.0V produces TTL level outputs that are compatible with standard TTL logic devices operating at VCC = 5.0V. At VCC = 2.7V, the part is compatible with JEDEC approved low voltage battery operation (LVBO) interface specifications. The device is also capable of standard 5-volt operation making it ideally suited for dual supply range systems or card products that are pluggable in both 3-volt and 5-volt hosts. Atmel’s AT27BV010 has additional features to ensure high quality and efficient production use. The Rapid™ Programming Algorithm reduces the time required to program the Block Diagram 2 AT27BV010 part and guarantees reliable programming. Programming time is typically only 100 µs/byte. 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. The AT27BV010 programs exactly the same way as a standard 5V AT27C010 and uses the same programming equipment. 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 AT27BV010 has the same Product Identification Code as the AT27C010. Both are programming compatible. 8 AT27BV010 05 AT27BV010 Rapid Programming Algorithm A 100 µs PGM pulse width is used to program. 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 100 µs PGM pulse without verification. Then a verification / reprogramming loop is executed for each address. In the event a byte fails to pass verification, up to 10 successive 100 µs pulses are applied with a verification after each pulse. If the byte fails to verify after 10 pulses have been applied, the part is considered failed. After the byte 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 bytes are read again and compared with the original data to determine if the device passes or fails. 9 Ordering Information ICC (mA) VCC = 3.6V tACC (ns) Active Standby 90 8 120 150 Ordering Code Package 0.02 AT27BV010-90JC AT27BV010-90TC AT27BV010-90VC 32J 32T 32V Commercial (0°C to 70°C) 8 0.02 AT27BV010-90JI AT27BV010-90TI AT27BV010-90VI 32J 32T 32V Industrial (-40°C to 85°C) 8 0.02 AT27BV010-12JC AT27BV010-12TC AT27BV010-12VC 32J 32T 32V Commercial (0°C to 70°C) 8 0.02 AT27BV010-12JI AT27BV010-12TI AT27BV010-12VI 32J 32T 32V Industrial (-40°C to 85°C) 8 0.02 AT27BV010-15JC AT27BV010-15TC AT27BV010-15VC 32J 32T 32V Commercial (0°C to 70°C) 8 0.02 AT27BV010-15JI AT27BV010-15TI AT27BV010-15VI 32J 32T 32V Industrial (-40°C to 85°C) Package Type 32J 32-Lead, Plastic J-Leaded Chip Carrier (PLCC) 32T 32-Lead, Plastic Thin Small Outline Package (TSOP) (8 x 20 mm) 32V 32 Lead, Plastic Thin Small Outline Package (VSOP) (8 x 14 mm) 10 AT27BV010 Operation Range AT27BV010 Packaging Information 32J, 32-Lead, Plastic J-Leaded Chip Carrier (PLCC) Dimensions in Inches and (Millimeters) JEDEC STANDARD MS-016 AE 32T, 32-Lead, Plastic Thin Small Outline Package (TSOP) Dimensions in Millimeters and (Inches)* JEDEC OUTLINE MO-142 BD .045(1.14) X 45˚ PIN NO. 1 IDENTIFY .025(.635) X 30˚ - 45˚ .012(.305) .008(.203) .553(14.0) .547(13.9) .595(15.1) .585(14.9) .032(.813) .026(.660) .050(1.27) TYP .300(7.62) REF .430(10.9) .390(9.90) AT CONTACT POINTS INDEX MARK .530(13.5) .490(12.4) 18.5(.728) 18.3(.720) 20.2(.795) 19.8(.780) .021(.533) .013(.330) .030(.762) .015(.381) .095(2.41) .060(1.52) .140(3.56) .120(3.05) 0.50(.020) BSC 7.50(.295) REF 0.25(.010) 0.15(.006) 8.20(.323) 7.80(.307) 1.20(.047) MAX 0.15(.006) 0.05(.002) .022(.559) X 45˚ MAX (3X) 0 5 REF .453(11.5) .447(11.4) .495(12.6) .485(12.3) 0.20(.008) 0.10(.004) 0.70(.028) 0.50(.020) *Controllling dimension: millimeters 32V, 32-Lead, Plastic Thin Small Outline Package (VSOP) Dimensions in Inches and (Millimeters) JEDEC OUTLINE MO-142 BA INDEX MARK 12.5(.492) 12.3(.484) 0.50(.020) BSC 7.50(.295) REF 14.2(.559) 13.8(.543) 0.25(.010) 0.15(.006) 8.10(.319) 7.90(.311) 1.20(.047) MAX 0.15(.006) 0.05(.002) 0 5 REF 0.20(.008) 0.10(.004) 0.70(.028) 0.50(.020) 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.
