AUTOMOTIVE 87C54/87C54-20
DATA SHEET REVISION HISTORY
The following are key differences between this data sheet and the -003 version of the data sheet.
1. The data sheet has been revised to include the 20 MHz 87C54. The title was changed from 87C54 to
87C54/87C54-20.
2. RST pin in Figure 3 has been changed to RESET pin.
3. Max I
CC
has been corrected to reflect test program conditions.
4. Figure 6, I
CC
vs. Frequency, has been changed to reflect new I
CC
specifications.
5. 87C54-20 A.C. Timings have been added to the External Memory Characteristics Table.
The following are key differences between this data sheet and the -002 version of the data sheet.
1. ‘‘NC’’ pin labels changed to ‘‘Reserved’’ in Figure 3.
2. Capacitor value for ceramic resonators deleted in Figure 4.
3. Replaced A0–A15 with P1.0–P1.7, P2.0–P2.5 (EPROM programming and verification waveforms).
4. Replaced D0–D7 with P0 (EPROM programming and verification waveforms).
The following are the key differences between the -001 and the -002 versions of this data sheet.
1. The RST description has been modified to clarify the reset operation when the oscillator is not running.
2. Figure 4 (Oscillator Connections) has been changed for Ceramic Resonators.
3. A description of RFI Reduction Mode has been added.
