The use of Pulse Width Timers for the generation of various waveforms is easily accomplished by the HPC46400E. Frequencies can be generated by using the timer/register pairs. A square wave is generated when the register value is a constant. The duty cycle can be controlled simply by changing the register value.
The HPC46400E is an upgraded HPC16400. Features have been added to support V.120, the 8-bit mode has been enhanced 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 HPC36400E serial interface decoder allows the 2 HDLC channels to be used with devices using interchip serial link for point-topoint and multipoint data exchanges. The decoder generates enable signals for the HDLC channels allowing multiplexed D and B channel data to be accessed.
The HPC36400E HDLC channels manage the link by providing sequencing 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 operation are supported.
The HPC36400E and HPC46400E are available in 68-pin PLCC and 80-pin PQFP packages.
