Description
The A29L004TL-70 is a 4Mbit, 3.0 volt-only Flash memory organized as 524,288 bytes of 8 bits. It is designed to be programmed in-system with the standard system 3.0 volt VCC supply, eliminating the need for additional 12.0 volt VPP for write or erase operations. It can also be programmed in standard EPROM programmers. The A29L004TL-70 is available in 40-pin TSOP, 32-pin PLCC or (s)TSOP packages.
Specifications and features
- Single power supply operation
- Full voltage range: 2.7 to 3.6 volt read and write operations for battery-powered applications
- Regulated voltage range: 3.0 to 3.6 volt read and write operations for compatibility with high performance 3.3 volt microprocessors
- Access times: 70/90 (max.)
- Current:
- 4 mA typical active read current
- 20 mA typical program/erase current
- 200 nA typical CMOS standby
- 200 nA Automatic Sleep Mode current
- Flexible sector architecture
- 16 Kbyte/8 KbyteX2/32 Kbyte/64 KbyteX7 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. Temporary Sector Unprotect feature allows code changes in previously locked sectors
- Unlock Bypass Program Command: Reduces overall programming time when issuing multiple program command sequence
- Top or bottom boot block configurations available
- Embedded 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 data at specified addresses
- Typical 100,000 program/erase cycles per sector
- 20-year data retention at 125°C: Reliable operation for the life of the system
- Compatible with JEDEC-standards: Pinout and software compatible with single-power supply Flash memory standard
- Superior inadvertent write protection
- Data Polling and toggle bits: Provides a software method of detecting completion of program or erase operations
- Ready / BUSY pin (RY / BY): Provides a hardware method of detecting completion of program or erase operations (not available on 32-pin PLCC & (s)TSOP packages)
- 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 32 pin PLCC & (s)TSOP packages)
- Package options: 40-pin TSOP (forward type), 32-pin PLCC or (s)TSOP (forward type)
Application Scenarios
The A29L004TL-70 is suitable for various electronic devices that require 3.0 volt-only Flash memory with high performance and low power consumption. It can be used in battery-powered applications, as well as devices that require compatibility with 3.3 volt microprocessors.
