COP87L84RK Datasheet | National Semiconductor

Description The COP888EB ROM based microcontrollers are highly integrated COP8™ Feature core devices with 8k memory and advanced features including a CAN 2.0B (passive) interface, A/D and USART. These single-chip CMOS devices are suited for applications requiring a full featured controller with a CAN interface, low EMI, and versatile munications interfaces. COP87L8EB/RB devices are pin and software patible 16k or 32k OTP (One Time Programmable) versions for pre-production, and for use with a range of COP8 software and hardware development tools.
