Overview
The HPC46003V20/63 is a 16-bit microcontroller manufactured by National Semiconductor, now part of Texas Instruments. It operates with a maximum clock frequency of 20 MHz and utilizes a PQCC68 plastic LCC-68 package containing 68 pins. The device features an 8-bit address bus width and a 16-bit external data bus width. It includes 52 I/O lines and supports PWM channels. The component lacks ADC, DAC, and DMA capabilities. It is rated for operation up to a maximum temperature of 70 °C.
Feature Summary
- 16-bit architecture with 20 MHz processing capability
- Integrated PWM channel support
- Extensive I/O connectivity via 52 lines
- Plastic LCC-68 surface mount packaging
Applications
- Industrial control systems requiring 16-bit processing
- Embedded applications utilizing PWM outputs
- General-purpose microcontroller tasks in commercial electronics
Procurement Notes
Verify the manufacturer designation carefully, as National Semiconductor assets were acquired by Texas Instruments. Confirm the specific suffix /63 corresponds to the required package variant. Ensure compatibility with existing design specifications regarding the 70 °C maximum operating temperature limit. Cross-reference pinout details against official datasheets to prevent integration errors during PCB assembly.
Selection Notes
Select this component when a 16-bit MCU with moderate speed is required. Consider the absence of ADC and DAC if analog interfaces are needed. Evaluate the 68-pin LCC package constraints for board space. Verify that the 20 MHz clock speed meets system timing requirements. Check availability through authorized distributors given the legacy status of the original brand.
Part Context
This microcontroller belongs to the HPC46003 series, representing legacy 16-bit embedded solutions from National Semiconductor. Following the acquisition by Texas Instruments, these parts are often referenced under TI branding or through specialized distributors like Rochester Electronics. The device serves as a foundational controller for older industrial and consumer electronic designs.
Replacement Considerations
Check for HPC46003V20/NOPB variants which indicate RoHS compliance. Verify functional equivalence with other 16-bit MCUs from the same family if sourcing new production units.
