The x16 organization makes this part ideal for portable and hand held 16- and 32-bit microprocessor based systems using either regulated or unregulated battery power. Atmel’s innovative design techniques provide fast speeds that rival 5V parts while keeping the low power consumption of a 3V supply. At V CC = 2.7V, any word can be accessed in less than 120ns. With a typical power dissipation of only 10 mW at 5mHZ and VCC = 3V, the AT27BV800 consumes less than one fifth the power of a standard 5V EPROM. Standby mode supply current is typically less than 1 mA at 3V. The AT27BV800 simplifies system design and stretches battery lifetime even further by eliminating the need for power supply regulation. The AT27BV800 can be organized as either word-wide or byte-wide. The organization is selected via the BYTE/VPP pin. When BYTE/VPP is asserted high (VIH), the word-wide organization is selected and the O15/A-1 pin is used for O15 data output. When BYTE/VPP is asserted low (V IL),the byte wide organization is selected and the O15/A-1 pin is used for the address pin A-1. When the AT27BV800 is logically regarded as x16 (word-wide), but read in the bytewide mode, then with A-1=VIL the lower eight bits of the 16 bit word are selected with A-1 =VIH the upper 8 bits of the 16-bit word are selected. The AT27BV800 is available in industry standard JEDECapproved one-time programmable (OTP) PLCC, SOIC (SOP), and TSOP packages. The device features two-line control(CE,OE) to eliminate bus contention in high-speed systems. With high density 512K word or 1024K-bit storage capability, the AT27BV800 allows firmware to be to be stored reliably and to be accessed by the system without the delays of mass storage media. Block Diagram 2 AT27BV800 The AT27BV800 operating with VCC at 3.0V produces TTL level outputs that are compatible with standard TTL logic devices operating at VCC = 5V. At V CC = 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 AT27BV800 has additional features that ensure high quality and efficient production use. The RapidTM Programming Algorithm reduces the time required to program the part and guarantees reliable programming. Programming time is typically only 50µs/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 equipment and voltages. The AT27BV800 programs exactly the same way as a standard 5V AT27C800 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 AT27BV800 has the same Product Identification Code as the AT27C800. Both are programming compatible. AT27BV800 AT27BV800 Rapid Programming Algorithm A 50 µs CE pulse width is used to program. The address is set to the first location. VCC is raised to 6.5V and BYTE/VPP is raised to 13.0V. Each address is first programmed with one 50 µs CE 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 ICC (mA) tACC (ns) Active Standby 120 10 150 Ordering Code Package Operation Range 0.02 AT27BV800-12JC AT27BV800-12RC AT27BV800-12TC 44J 44R 48T Commercial (0°C to 70°C) 10 0.02 AT27BV800-12JI AT27BV800-12RI AT27BV800-12TI 44J 44R 48T Industrial (-40°C to 85°C) 10 0.02 AT27BV800-15JC AT27BV800-15RC AT27BV800-15TC 44J 44R 48T Commercial (0°C to 70°C) 10 0.02 AT27BV800-15JI AT27BV800-15RI AT27BV800-15TI 44J 44R 48T Industrial (-40°C to 85°C) = Preliminary Package Type 44J 44-Lead, Plastic J-Leaded Chip Carrier (PLCC) 44R 44-Lead, 0.525" Wide, Plastic Gull Wing Small Outline Package (SOIC/SOP) 48T 48-Lead, Plastic Thin Small Outline Package (TSOP) 12 x 20 mm 10 AT27BV800 AT27BV800 Packaging Information 44R, 44-Lead, 0.525" Wide, Plastic Gull Wing Small Outline Package (SOIC/SOP) Dimensions in Inches and (Millimeters) 48T, 48-Lead, 12 x 20 mm, Plastic Thin Small Outline Package(TSOP) Dimensions in Millimeters and (Inches)* JEDEC OUTLINE MO-142 BD *Controlling dimension: millimeters 44J, 44-Lead, Plastic J-Leaded Chip Carrier (PLCC) Dimensions in Inches and (Millimeters) JEDEC STANDARD MS-018 AC .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
