Memory IC datasheet and documents for M29W200BB70M1
Memory IC Overview
The M29W200BB70M1 is a 2 Mbit (256Kb x8 or 128Kb x16) low voltage single supply flash memory featuring a bottom boot block architecture. It operates on a 2.7V to 3.6V supply with an access time of 55ns and typical programming time of 10µs per byte/word. The device includes an embedded program/erase controller, supports erase suspend/resume modes, and offers 100,000 program/erase cycles per block with 20 years data retention. It is available in TSOP48 and SO44 packages.
Memory IC Feature Summary
- Embedded Program/Erase Controller for simplified operation
- Bottom Boot Block configuration for secure code storage
- Erase Suspend and Resume capabilities
- Temporary Block Unprotection Mode
Memory IC Applications
- Microprocessor initialization code storage
- Parameter storage applications
- Application code storage in embedded systems
Memory IC Procurement Notes
Verify the specific suffix '70M1' against official STMicroelectronics documentation to confirm exact package type and temperature range options. Ensure compatibility with system voltage requirements of 2.7V to 3.6V. Confirm pinout alignment for either TSOP48 or SO44 packaging as specified in the datasheet.
Memory IC Selection Notes
Select this component for designs requiring a dedicated bottom boot block for reliable microprocessor startup code. Consider the 55ns access speed and single-supply operation for low-power embedded applications. Verify that the 2 Mbit capacity fits the application's memory constraints and that the SO44 or TSOP48 package suits the PCB layout.
Memory IC Part Context
The M29W200B series is a non-volatile memory family backward compatible with the M29W200. The M29W200BB variant specifically designates the Bottom Boot Block arrangement, distinguishing it from the Top Boot Block M29W200BT. This series utilizes a command interface consistent with JEDEC standards for standard bus operations.
Memory IC Replacement Considerations
The M29W200BT serves as a functional alternative if a top boot block configuration is acceptable instead of the bottom boot block structure found in the M29W200BB.
