Active production — BOM-fit for 2Kbit serial EEPROM
The AT93C56B-MAHM-T is an active-production 2Kbit serial EEPROM from Microchip Technology, organized as 256 x 8 or 128 x 16 bits and accessed via a 3-wire interface. The 2 MHz clock frequency supports moderate-speed parameter storage in embedded control applications.
Package and board integration — 8-UFDFN with exposed pad
Housed in an 8-UFDFN Exposed Pad package (supplier device package 8-Mini Map 2x3 mm), the part requires a surface-mount footprint with a thermal pad for heat sinking. The exposed paddle must be soldered to a PCB copper plane to meet the datasheet thermal resistance.
Write cycle and endurance for field updates
This is fast enough for infrequent calibration or configuration updates in a production test sequence. The 3-wire serial interface (chip select, clock, data I/O) is compatible with standard SPI-like controllers; no pull-up resistors are required on the data line if the master drives it actively.
ROHS3 compliant — no restricted substances above the threshold per EU Directive 2015/863.
