The Static Memory Controller (SMC) generates the signals that control the access to the exter-
nal memory devices or peripheral devices. It has 4 chip selects and a 24-bit address bus. The
16-bit data bus can be configured to interface with 8-16-bit external devices. Separate read and
write control signals allow for direct memory and peripheral interfacing. Read and write signal
waveforms are fully parametrizable.
The SMC can manage wait requests from external devices to extend the current access. The
SMC is provided with an automatic slow clock mode. In slow clock mode, it switches from user-
programmed waveforms to slow-rate specific waveforms on read and write signals. The SMC
supports asynchronous burst read in page mode access for page size up to 32 bytes.
4 chip selects available
16-Mbytes address space per chip select
8- or 16-bit data bus
Word, halfword, byte transfers
Byte write or byte select lines
Programmable setup, pulse and hold time for read signals per chip select

Compliant with LCD module
External wait request
Automatic switch to slow clock mode
Asynchronous read in page mode supported: page size ranges from 4 to 32 bytes
