Preliminary Data Sheet

Lucent Technologies Inc.
Microprocessor Interface
The host interface is designed to connect directly to a typical synchronous or asynchronous host bus. The interface
to the TTSI2K32T includes a separate clock, PCLK, which is used only in the synchronous interface mode. This
device will be a slave on the host bus and will provide the host microprocessor with the capability to read and write
the TTSI2K32T address space in a minimal number of clock cycles. There is no posting of writes in the host inter-
face, and all registers and the data and connection stores are directly accessible.
Asynchronous Mode (MM = 0)
The following two timing diagrams show read and write in the asynchronous mode.
5-6954(F).r3
Figure 5. Asynchronous Read
5-6955(F)r.3
Figure 6. Asynchronous Write
The presence of AS, CS, and DS being asserted will start the TTSI2K32T internal access. Once data has been
retrieved or written, DT will be asserted indicating the TTSI2K32T is ready to terminate the access. DT will continue
to be asserted until AS, CS, or DS is negated.
The duration of an asynchronous read or write cycle will be a maximum of 183 ns. This duration is measured from
when AS, CS, and DS are all asserted low until DT is asserted low by the TTSI2K32T.
