Description
AT25128B-MAHL-E is an Atmel (Microchip) 128-kbit serial EEPROM with a SPI interface. It provides non-volatile storage with fast random access, suitable for configuration data, calibration constants, and small firmware parameters.
Key points
- Capacity/organization: 128 Kb, typically 16K × 8
- Interface: SPI (SCK, SI, SO, CS)
- Voltage: 2.7–5.5 V
- Speed: up to tens of MHz (typical SPIs up to ~40 MHz)
- Memory operations: Read, Write Enable/Disable, Write/Write Status Register, page write
- Page size: commonly 16 bytes; write cycle time ~a few ms
- Endurance/Data retention: around 1 million write cycles; long data retention
- Packaging: -MAHL-E denotes a specific RoHS-compliant 8-pin package option (often an SOIC-8 variant); exact mechanicals/temperature range vary by grade—check the datasheet for details
Use cases: microcontroller config storage, calibration tables, small data logs. For precise specs and the exact package/temperature options, consult the AT25128B datasheet.
