Note

1. PCF7941ATJ/CA1B00E0 represents the E-ROM product for development and applications with low quantities. The customer

shall perform E-ROM programming and EEPROM initialization. The Monitor and Download Interface (MSDA/MSCL)

supports E-ROM download and ERASE/WRITE as fast as 700ms for 4 kByte.

2. PCF7941ATJ/CA1Brrff represents a customized E-ROM product. Under certain conditions NXP Semiconductors may

perform E-ROM programming with a customer application code and/or customer EEPROM pattern. The actual customer

application code and customer EEPROM fabkey is specified by a 2 digit code at location marked “ff”. The ROM code is

specified by a 2 digit code at location marked „rr“

2. PCF7341ATJ/C0ABrrff represents the ROM coded product for high volume applications. The actual customer ROM code

and customer EEPROM fabkey is specified by a 2 digit code at location marked „rr“, respectively “ff”
