The x16 data appears on I/O0 - I/O15 the x8 data appears on I/O0 - I/O7. The memory is divided into 71 sectors for erase operations. The device is offered in a 48-lead TSOP and a 48-ball CBGA package. The device has CE and OE control signals to avoid any bus contention. This device can be read or reprogrammed using a single power supply, making it ideally suited for in-system programming. The device powers on in the read mode. Command sequences are used to place the device in other operation modes such as program and erase. The device has the capability to protect the data in any sector see “Sector Lockdown” on page To increase the flexibility of the device, it contains an Erase Suspend and Program Suspend feature. This feature will put the erase or program on hold for any amount of time and let the user read data from or program data to any of the remaining sectors within the memory. The end of a program or an erase cycle is detected by the READY/BUSY pin, Data Polling or by the toggle bit. The VPP pin provides data protection. When the VPP input is below 0.4V, the program and erase functions are inhibited. When VPP is at 0.9V or above, normal program and erase operations can be performed. A six-byte command Enter Single Pulse Program Mode sequence to remove the requirement of entering the three-byte program sequence is offered to further improve programming time. After entering the six-byte code, only single pulses on the write control lines are required for writing into the device. This mode Single Pulse Byte/Word Program is exited by powering down the device, or by pulsing the RESET pin low for a minimum of 500 ns and then bringing it back to VCC. Erase, Erase Suspend/Resume and Program Suspend/Resume commands will not work while in this mode if entered they will result in data being programmed into the device. It is not recommended that the six-byte code reside in the software of the final product but only exist in external programming code. The BYTE pin controls whether the device data I/O pins operate in the byte or word configuration. If the BYTE pin is set at logic “1”, the device is in word configuration, I/O0 - I/O15 are active and controlled by CE and OE. If the BYTE pin is set at logic “0”, the device is in byte configuration, and only data I/O pins I/O0 - I/O7 are active and controlled by CE and OE. The data I/O pins I/O8 - I/O14 are tri-stated, and the I/O15 pin is used as an input for the LSB A-1 address function. 2 AT49BV322A T Pin Configurations Pin Name A0 - A20 CE OE WE RESET RDY/BUSY VPP I/O0 - I/O14 I/O15 A-1 BYTE NC TSOP Top View Type 1 AT49BV322A T Function Addresses Chip Enable Output Enable Write Enable Reset READY/BUSY Output Write Protection Data Inputs/Outputs I/O15 Data Input/Output, Word Mode A-1 LSB Address Input, Byte Mode Selects Byte or Word Mode No Connect A15 1 A14 2 A13 3 A12 4 A11 5 A10 6 A9 7 A8 8 A19 9 A20 10 WE 11 RESET 12 NC 13 VPP 14 RDY/BUSY 15 A18 16 A17 17 A7 18 A6 19 A5 20 A4 21 A3 22 A2 23 A1 24 48 A16 47 BYTE 46 GND 45 I/O15/A-1 44 I/O7 43 I/O14 42 I/O6 41 I/O13 40 I/O5 39 I/O12 38 I/O4 37 VCC 36 I/O11 35 I/O3 34 I/O10 33 I/O2 32 I/O9 31 I/O1 30 I/O8 29 I/O0 28 OE 27 GND 26 CE 25 A0 CBGA Top View Ball Down 123456 A3 A7 RDY/BUSY WE A9 A13 A4 A17 VPP RST A8 A12 A2 A6 A18 NC A10 A14 A1 A5 A20 A19 A11 A15 A0 I/O0 I/O2 I/O5 I/O7 A16 CE I/O8 I/O10 I/O12 I/O14 BYTE OE I/O9 I/O11 VCC I/O13 I/015/A-1 VSS I/O1 I/O3 I/O4 I/O6 VSS Block Diagram I/O0 - I/O15/A-1 OUTPUT BUFFER INPUT BUFFER A0 - A20 INPUT BUFFER ADDRESS LATCH Y-DECODER X-DECODER Ordering Information Standard Package tACC ICC mA Active Standby Ordering Code AT49BV322A-70CI AT49BV322A-70TI AT49BV322AT-70CI AT49BV322AT-70TI Green Package Option Pb/Halide-free tACC ICC mA Active Standby Ordering Code AT49BV322A-70CU AT49BV322A-70TU AT49BV322AT-70CU AT49BV322AT-70TU AT49BV322A T Package 48C17 48T 48C17 48T Operation Range Industrial -40° to 85°C Industrial -40° to 85°C Package 48C17 48T 48C17 48T Operation Range Industrial -40° to 85°C Industrial -40° to 85°C 48C17 48T Package Type 48-ball, Plastic Chip-Size Ball Grid Array Package CBGA 48-lead, Plastic Thin Small Outline Package TSOP Packaging Information 48C17 CBGA A1 Ball ID A B C D E F G H Top View A1 Ball Corner 6 54321 Bottom View Side View COMMON DIMENSIONS Unit of Measure = mm SYMBOL E E1 D D1 A A1 e Øb NOM TYP BSC TYP NOTE TITLE 2325 Orchard Parkway 48C17, 48-ball 6 x 8 Array , mm Pitch, R San Jose, CA 95131 x mm Chip-scale Ball Grid Array Package CBGA 12/10/02 48C17 30 AT49BV322A T 48T TSOP PIN 1 AT49BV322A T 0º ~ 8º c Pin 1 Identifier SEATING PLANE
