PRELIMINARY
November 1992
HPC36400EHPC46400E
High-Performance Communications MicroController
General Description
The HPC46400E is an upgraded HPC16400 Features have
been added to support V120 the 8-bit mode has been en-
hanced to support all instructions and the UART has been
changed to provide more flexibility and power
The
HPC46400E is fully upward compatible with the HPC16400
The HPC46400E has 4 functional blocks to support a wide
range of communication application-2 HDLC channels 4
channel DMA controller to facilitate data flow for the HDLC
channels programmable serial interface and UART
The serial interface decoder allows the 2 HDLC channels to
be used with devices using interchip serial link for point-to-
point and multipoint data exchanges The decoder gener-
ates enable signals for the HDLC channels allowing multi-
plexed D and B channel data to be accessed
The HDLC channels manage the link by providing sequenc-
ing using the HDLC framing along with error control based
upon a cyclic redundancy check (CRC) Multiple address
recognition modes and both bit and byte modes of opera-
tion are supported
The HPC36400E and HPC46400E are available in 68-pin
PLCC and 80-pin PQFP packages
