1 / 3 page Rev. 4179B–8051–10/02 Active Errata List • Power-down Mode Current Out of Specification in ROMless Mode • Power-fail Threshold Out of Specification • TWI Data Transmission in Slave Transmitter Mode Errata History Errata Description 1. Power-down Mode Current Out of Specification in ROMless Mode IPD is out of specification when EA pin is tied to a low level. The ROMless products and EPROM and ROM products used as ROMless (EA = 0) are consuming extra current in power-down mode. Table 1 below shows the power-down current maxi- mum value and specification for high speed in low voltage versions. Workaround None. 2. Power-fail Threshold Out of Specification The tolerance on the power-fail reset voltage threshold is out of specification. The device may never exit reset at power-up when power-fail reset is enabled. Workaround Some devices may need a higher voltage to exit reset. The RSTD bit has to be set in POWM register to disable the Power-fail Reset detector before the voltage is reduced. 3. Two-wire Interface Data Transmission in Slave Transmitter Mode When in slave transmitter mode, if the slave transmits data starting with a low level on the bus (MSB is logic 0), data set-up time is not respected and leads to a bus error. Workaround The workaround proposed consists in removing the set-up violation by stretching the SDA line (P1.7) when the MSB of the data to transmit is logic 0. This workaround must be implemented in states A8h, B0h, and B8h when data is writ- ten to the serial data register (SSDAT).
