This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
MCU BUS INTERFACE
The “no-glue logic” MCU Bus Interface block can
be directly connected to most popular 8-bit and 16-
bit MCUs and their control signals. Key MCUs,
with their bus types and control signals, are shown
in Table 34. The MCU interface type is specified
using the PSDsoft.
Table 34. 16-bit MCUs and Their Control Signals
Note: 1. Unused CNTL2 pin can be configured as CPLD input. Other unused pins (PD3-PD0, PF3-PF0) can be configured for other I/O func-
tions.
2. ALE/AS input is optional for MCUs with a non-multiplexed bus.
3. This configuration is for MC68HC812A4_EC at 5MHz, 3V only.
