... 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. 3308D–FLASH–5/ 0.9V or above, normal program and erase opera- PP ...

... BYTE/WORD PROGRAMMING: Once a memory block is erased programmed (to a logi- cal “0” byte-by-byte word-by-word basis. Programming is accomplished via the internal device command register and is a four-bus cycle operation. The device will automati- cally generate the required internal program pulses. 3308D–FLASH–5/03 AT49BV32XA( ...

... Once I/O7 has gone high, status information on the other pins can be checked. The Data Polling status bit must be used in conjunction with the erase/program and V bit as shown in the algorithm in Figures 1 and 2 on page 10. AT49BV32XA(T) 6 voltage is less that 0.4V.

... PRODUCT IDENTIFICATION: The product identification mode identifies the device and man- ufacturer as Atmel. It may be accessed by hardware or software operation. The hardware operation mode can be used by an external programmer to identify the correct programming algorithm for the Atmel product. ...

... CFI allows system software to query the installed device to deter- mine the configurations, various electrical and timing parameters, and functions supported by the device. CFI is used to allow the system to learn how to interface to the flash device most optimally. The two primary benefits of using CFI are ease of upgrading and second source availability ...
