DATA SHEET REVISION SUMMARY
The following represent the key differences between 02/20/97 and 07/07/98 version of the DS87C530
data sheet. Please review this summary carefully.
1. Add DS83C530 to data sheet.
2. Updated PMM operating current estimates.
3. Added note to clarify IIL specification.
4. Added note to prevent accidental corruption of Watchdog Timer count while changing counter length.
5. Changed IBAT specification to 1
A over extended temperature range.
6. Changed minimum oscillator frequency to 1 MHz when using external crystal.
7. Changed RST pulldown resistance from 170 k
=to 200 k=maximum.
8. Corrected “Data memory write with stretch” diagrams to show falling edge of ALE coincident with
rising edge of C3 clock.
The following represent the key differences between 06/08/95 and 02/20/97 version of the DS87C530
data sheet. Please review this summary carefully.
1. Update ALE pin description.
2. Add note pertaining to erasure window.
3. Add note pertaining to internal MOVX SRAM.
4. Change Note 6 from RST=5.5V to RST=VCC.
5. Change Note 10 from RST=5.5V to RST=VCC.
6. Change serial port mode 0 timing diagram label from tQVXL to tQVXH.
7. Add information pertaining to 52-pin TQFP package.
