IS29GL256
IS29GL256 is 256M-BIT 3.0V PAGE MODE PARALLEL FLASH MEMORY manufactured by ISSI.
FEATURES
- Single power supply operation
- Full voltage range: 2.7 to 3.6 volts read and write operations
- Fast Access Time at -40°C to +125°C:
- 70ns (1) at Vcc = 3.0V~3.6V, VIO = 3.0V~3.6V
- VIO Input/Output 1.65V to 3.6V.
- All input levels (address, control, and DQ input levels) and outputs are determined by voltage on VIO input.
- 8-word/16-byte page read buffer
- 32-word/64-byte write buffer reduces overall programming time for multiple-word updates
- Secured Silicon Region (SSR)
- 512-word/1024-byte sector for permanent, secure identification
- 256-word Factory Locked SSR and 256-word
Customer Locked SSR
- Uniform 64Kword/128KByte Sector Architecture
- Suspend and Resume mands for Program and Erase operations
- Write operation status bits indicate program and erase operation pletion
- Support for CFI (mon Flash Interface)
- Volatile and non-volatile methods of Advanced Sector Protection
- WP#/ACC input
- Accelerates programming time (when VHH is applied) for greater throughput during system production
- Protects first or last sector regardless of sector protection settings
- Hardware reset input (RESET#) resets device
- Ready/Busy# output (RY/BY#) detects program or erase cycle pletion
- Minimum 100K program/erase endurance cycles.
- Data retention : 20 years (TYP)
- Package Options
- 56-pin TSOP
- 64-ball 13mm x 11mm BGA (Call Factory)
- 64-ball 9mm x 9mm BGA

Note: 1. 80ns at Vcc=2.7V~3.6V, VIO=2.7V~3.6V.
90ns at Vcc=2.7V~3.6V, VIO=1.65V ~ Vcc.
GENERAL DESCRIPTION
The IS29GL256/128 offer a fast page access time of 20ns with a corresponding random access time as fast as 70ns. It features a Write Buffer that allows a maximum of 32 words/64 bytes to be programmed in one operation, resulting in faster effective programming time than standard programming algorithms. This makes the device ideal for today’s embedded applications that...
