Memory IC datasheet and documents for AT29BV020-12TU
Memory IC Overview
The AT29BV020-12TU is a 2-megabit (256K x 8) single-supply Flash PEROM manufactured by Microchip Technology. It operates within a voltage range of 2.7V to 3.6V and features a fast read access time of 120 ns. The device utilizes a 32-lead TSOP package and supports industrial temperature ranges from -40°C to +85°C. Key electrical characteristics include an active current of 15 mA and a CMOS standby current of 50 µA.
Memory IC Feature Summary
- Supports software protected programming with sector-based operations
- Includes two 8K byte boot blocks with independent lockout capabilities
- Features internal program control, timers, and DATA polling for cycle detection
- Provides hardware data protection against inadvertent programming
Memory IC Applications
- In-system reprogrammable code storage
- Boot block memory for system initialization
- Nonvolatile data storage in embedded systems
Memory IC Procurement Notes
Verify the manufacturer origin as Atmel or Microchip Technology due to corporate acquisition history. Confirm the specific suffix TU indicates the 32-lead Thin Small Outline Package (TSOP). Ensure the ordering code matches the 120 ns access speed requirement. Check for RoHS compliance documentation regarding green packaging options.
Memory IC Selection Notes
Select this component when a 2-megabit capacity with 120 ns access speed is required. The TSOP package is suitable for surface mount applications. Verify that the system design accommodates the 2.7V to 3.6V supply range. Consider the sector size of 256 bytes for programming granularity requirements.
Memory IC Part Context
This part belongs to the AT29BV series of low-voltage Flash memory devices. It shares architectural similarities with other members like the AT29BV040 but offers half the density. The device is designed for compatibility with standard EPROM interfaces while providing nonvolatile flash capabilities.
Memory IC Replacement Considerations
AT29BV020-15TU provides identical functionality with a slower 150 ns access time.
