80C51XA
The Philips 80C51XA MCU family supports an 8-
or 16-bit multiplexed bus that can have burst cy-
cles. Address bits (A3-A0) are not multiplexed,
while (A19-A4) are multiplexed with data bits
(D15-D0) in 16-bit mode. In 8-bit mode, (A11-A4)
are multiplexed with data bits (D7-D0).
The 80C51XA can be configured to operate in
eight-bit data mode (as shown in Figure 24).
The 80C51XA improves bus throughput and per-
formance by executing burst cycles for code fetch-
es. In Burst Mode, address A19-A4 are latched
internally by the PSD, while the 80C51XA changes
the A3-A0 signals to fetch up to 16 bytes of code.
The PSD access time is then measured from ad-
dress A3-A0 valid to data in valid. The PSD bus
timing requirement in Burst Mode is identical to the
normal bus cycle, except the address setup and
hold time with respect to Address Strobe (ALE/AS,
PD0) does not apply.
