... GND is recommended for designs that switch V off during read operation. CCW 1.2 Product Overview The LH28F320BJHE-PBTLZU is a high-performance 32M-bit Boot Block Flash memory organized as 2M-word of 16 bits or 4M-byte of 8 bits. The 2M-word/4M-byte of data is arranged in two 4K-word/8K-byte boot blocks, six 4K-word/8K-byte parameter blocks and sixty-three 32K- word/64K-byte main blocks which are individually erasable, lockable and unlockable in-system ...

... PRINCIPLES OF OPERATION The LH28F320BJHE-PBTLZU flash memory includes an on-chip WSM to manage block erase, full chip erase, word/byte write and lock-bit configuration functions. It allows for: fixed power supplies during block erase, full chip erase, word/byte write and lock-bit configuration, and minimal processor overhead with RAM-like interface timings ...

... If a CPU reset occurs with no flash memory reset, proper CPU initialization may not occur because the flash memory may be providing status information instead of array data. SHARP’s flash memories allow proper CPU initialization following a system reset through the use of the RP# input. In this ...

... The OTP block is a special block that can not be erased. The block is divided into two parts. One is a factory program area where a unique number can be written according to customer requirements in SHARP factory. This factory program area is "READ ONLY" (Already locked). The other is a customer program area that can be used by customers ...

... If the permanent lock-bit is set, Set Block Lock-Bit and Clear Block Lock-Bits commands can not be done. 9. Once the permanent lock-bit is set, permanent lock-bit reset is unable. 10. Commands other than those shown above are reserved by SHARP for future device implementations and should not be used. ...

Page 16

Read Array Command Upon initial device power-up and after exit from reset mode, the device defaults to read array mode. This operation is also initiated by writing the Read Array command. The device remains enabled for reads until another ...

Page 17

Block Erase Command Erase is executed one block at a time and initiated by a two-cycle command. A block erase setup is first written, followed by an block erase confirm. This command sequence requires appropriate sequencing and an address ...

Page 18

Block Erase Suspend Command The Block Erase Suspend command allows block-erase interruption to read or word/byte write data in another block of memory. Once the block erase process starts, writing the Block Erase Suspend command requests that the WSM ...

Page 19

Set Block and Permanent Lock-Bit Commands A flexible block locking and unlocking scheme is enabled via a combination of block lock-bits, a permanent lock-bit and WP# pin. The block lock-bits and WP# pin gates program and erase operations while ...
