Each member of the family has a similar core CPU with unique memory, resources, and I/O configuration to suit specific applications. The HPC46100 is fabricated in National's advanced microCMOS technology. This process combined with an advanced architecture provides fast, flexible I/O control, efficient data manipulation, high speed computation, and low power consumption.
Throughput is enhanced by operating the HPC46100 at frequencies up to 40 MHz, by integrating a Multiply/Accumulate Unit (MAU) onto the chip, and by optimizing instructions to increase efficiency. These features increase performance in closed loop digital servo and filter applications.
The HPC46100 devices are complete microcomputers on a single chip. All system timing, internal logic, RAM, and I/O are provided on the chip to produce a cost effective solution for high performance applications. On-chip functions such as an MAU unit, PWM outputs, Chip Select Signals, UART, up to seven 16-bit timers with input capture capability, WATCHDOGTM logic, vectored interrupts, and MICROWIRE/PLUSTM provide a high level of system integration. The ability to directly address up to 64 kbytes of memory enables the HPC46100 to be used in powerful applications typically performed by microprocessors and peripheral chips.
The HPC46100 has, as an on-chip peripheral, an 8-channel 8-bit Analog-to-Digital Converter. This A/D converter can operate in a single-ended mode where the analog input voltage is applied across one of the eight input channels (D0± D7) and AGND. The A/D converter can also operate in a differential mode where the analog input voltage is applied across two adjacent input channels. The A/D converter will convert up to eight channels in the single-ended mode and up to four channel pairs in the differential mode.
A group of three high speed timers of HPC46100 provide processor independent PWM signal generation. These timers and their support logic provide independent control of PWM frequency and PWM duty cycle with a minimum resolution of 50 ns when running at 40 MHz.
The HPC46100 is upwards source code compatible with the HPC family except for Decimal Add and Subtract. It is available in an 80-pin QFP package.
