Industry’s first SPI-compatible 125°C double cell EEPROMs for automotive applications
(Technology News, 10 Sep 2007 )
ROHM has developed the industry’s first SPI-compatible BR25Hxx0 EEPROMs (non-volatile memory) for applications exposed to harsh environmental conditions such as automotive ECUs, where damage is a possibility due to surges and static electricity during startup and vibration and heat during operation. Features include double-cell construction, guaranteed operation at 125°C, the industry’s highest ESD resistance (6kV), gold pad/gold wire connections, and double reset functionality for high reliability. High redundancy circuits and processes combined with thorough screening and debugging ensure 1 million rewrites at 85°C and 300,000 rewrites at 125°C.
The new lineup consists of 12 models in different packages types and memory capacities.
Major features of the BR25Hxx0 Series: 1) Memory cell failures eliminated due to double-cell construction. 2) Wide operating temperature range: −40° to +125°C. 3) High ESD resistance: 6kV typ. (HBM) 4) Gold pad-Gold wire connections for greater reliability 5) Built in power supply monitoring circuit with double reset function 6) High speed Write and Page Write modes 7) SPI bus compatibility for easy replacement 8) Two package types available: SOP8 (6.2mm × 5.0mm × 1.71mm) and SOP-J8 (6.0mm × 4.9mm × 1.75mm)
