Manufacturer:ALTERA Description:mands are provided to allow protection of some or all of the blocks and to cancel all block protection bits simultaneously. All Program or Erase opera- tions are blocked when the Program Erase Enable input VPEN is low. The Reset/Power-Down pin is used to apply a Hardware Reset to the enabled memory and to set the device in power-down mode. The STS signal is an open drain output that can be used to identify the Program/Erase Controller sta- tus. It can be configured in two modes: Ready/ Busy mode where a static signal indicates the sta- tus of the P/E.C, and Status mode where a pulsing signal indicates the end of a Program or Block Erase operation. In Status mode it can be used as a system interrupt signal, useful for saving CPU time. The Bus operations of the device are controlled by Output Enable, Write Enable and three different Chip Enables. Refer to Table 2, Device Enable, for all possible combinations to enable and disable the device. Together they allow simple, yet power- ful, connection to most microprocessor, often with- out additional logic. The device includes a 128 bit Protection Register. The Protection Register is divided into two 64 bit segments, the first one is written by the manufac- turer (contact STMicroelectronics to define the code to be written here), while the second one is programmable by the user. The user programma- ble segment can be locked. The memory is available in TSOP56 (14 x 20 mm) and TBGA64 (10x13mm, 1mm pitch) packages. |
