J1850 8-Bit 68HC05 Microcontroller
Features
Description
• Fully Supports VPW Specifications of SAE J1850
Standard for Class B Data Communications Network
Interface
The HIP7030A2 HCMOS Microcomputer is a member of the
CDP68HC05 family of low-cost single-chip microcomputers.
The integrated hardware functions provide the system
designer with a complete set of building blocks for
implementing a “Class B” multiplexed communications net-
work interface, which fully conforms to the VPW Multiplexed
Wiring protocol specified in SAE Recommended Practice
J1850. This 8-bit microcomputer unit (MCU) contains an on-
chip oscillator, CPU, 176 bytes of RAM, 2110 bytes of user
ROM, 13 I/O lines, a J1850 Variable Pulse Width Symbol
Encoder/Decoder (VPW SENDEC) system, a Serial Periph-
eral Interface (SPI) system, a two channel analog Compara-
tor, a Watchdog Timer, a Slow Clock Detect, and a 16-bit
Timer. The static HCMOS design allows operation at input
frequencies up to 10MHz (5MHz internal clock).
