J1850 8-Bit 68HC05 Microcontroller

8K EEPROM Version

Description

The HIP7038A8 HCMOS Microcomputer is an EEPROM
version of the HIP7030A family of low-cost single-chip J1850
microcontrollers. These microcontrollers provide the system
designer with a complete set of building blocks for imple­menting a “Class B” VPW multiplexed communications
network interface, which fully complies with SAE Recom­mended Practice J1850. The HIP7038A8 contains all hard­ware and software features of the HIP7030A2/A8
microcontrollers with equivalent timing, performance charac­teristics, and an identical footprint.

The device can be programmed using the HIP7038A8
EEPROM Programmer available from Intersil. In-circuit
Emulation Tools are also provided for system development.
