Description
The A290021T-70 is a 5.0 volt-only Flash memory component organized as 262,144 bytes of 8 bits each. It offers the RESET function, except for the A290021 model. The data is divided into seven sectors for flexible sector erase capability. The A290021T-70 is available in 32-pin PLCC, TSOP, and PDIP packages. It can be programmed in-system with the standard system 5.0 volt VCC supply and does not require an additional 12.0 volt VPP. 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: A hardware method of protecting sectors to prevent any inadvertent program or erase operations within that sector
- 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)
Application Scenarios
The A290021T-70 Flash memory component can be used in various electronic devices and systems that require non-volatile memory for data storage and retrieval. It is suitable for applications where 5.0 volt-only operation is required, and where flexible sector erase capability is desired. It can be used in embedded systems, consumer electronics, automotive applications, and more.
