HPC36400E/HPC46400E
High-Performance Communications MicroController
General Description
The HPC46400E is an upgraded HPC16400. Features have
been added to support V.120, 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.
