COP884BC 8-Bit CMOS ROM Based Microcontrollers with 2k Memory, Comparators, and CAN Interface
General Description
The following part number is a pin count and temperature variation of the COP884BC: COP885BC. The COP884BC ROM based microcontrollers are highly integrated COP8TM Feature core devices with 2k memory and advanced features including a CAN 2.0B (passive) interface and two Analog comparators. These single-chip CMOS devices are suited for applications requiring a full featured controller with a CAN interface, low EMI, and an 8-bit 39 kHz PWM timer. COP87L84BC devices are pin and software compatible 16k OTP (One Time Programmable) versions for pre-production, and for use with a range of COP8 software and hardware development tools.

Note 4: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at VCC or GND, and outputs open. Note 5: The HALT mode will stop CKI from oscillating in the Crystal configurations. Halt test conditions: All inputs tied to VCC; L, and G port I/Os configured as outputs and programmed low; D outputs programmed low. Parameter refers to HALT mode entered via setting bit 7 of the G Port data register. Part will pull up CKI during HALT in crystal clock mode. Note 6: HALT and IDLE current specifications assume CAN block and comparators are disabled.
