Description
The A290021TL-70F is a 5.0 volt-only Flash memory organized as 262,144 bytes of 8 bits each. It offers a flexible sector erase capability with 256 Kbytes of data divided into seven sectors. The device is designed to be programmed in-system with a standard system 5.0 volt VCC supply and does not require an additional 12.0 volt VPP for write or erase operations. However, it can also be programmed in standard EPROM programmers.
Specifications and features
- 5.0V ± 10% for read and write operations
- Access times: 55/70/90/120/150 (max.)
- Current: - 20 mA typical active read current - 30 mA typical program/erase current - 1 mA typical CMOS standby
- Flexible sector architecture: - 16 Kbyte/ 8 KbyteX2/ 32 Kbyte/ 64 KbyteX3 sectors - Any combination of sectors can be erased - Supports full chip erase - Sector protection
- Top or bottom boot block configurations available
- Embedded Erase Algorithms: - Embedded Erase algorithm will automatically erase the entire chip or any combination of designated sectors and verify the erased sectors - Embedded Program algorithm automatically writes and verifies bytes at specified addresses
- Typical 100,000 program/erase cycles per sector
- 20-year data retention at 125°C
- Compatible with JEDEC-standards: - Pinout and software compatible with single-powersupply Flash memory standard - Superior inadvertent write protection
- Data Polling and toggle bits: - Provides a software method of detecting completion of program or erase operations
- Erase Suspend/Erase Resume: - Suspends a sector erase operation to read data from, or program data to, a non-erasing sector, then resumes the erase operation
- Hardware reset pin (RESET): - Hardware method to reset the device to reading array data (not available on A290021)
- Package options: - 32-pin P-DIP, PLCC, or TSOP (Forward type)
