September 1999
COP87L88EB/RB Family 8-Bit CMOS OTP Microcontrollers with 16k or 32k Memory, CAN Interface, 8-Bit A/D, and USART
General Description
The COP87L88EB/RB Family OTP (One Time programmable) microcontrollers are highly integrated COP8TM Feature core devices with 16k or 32k memory and advanced features including a CAN 2.0B (passive) interface, A/D and USART. These multi-chip CMOS devices are suited for applications requiring a full featured controller with a CAN interface, low EMI, and versatile communications interfaces, and as pre-production devices for ROM designs. Pin and software compatible 8k ROM versions (COP888EB) are available as well as a range of COP8 software and hardware development tools. Device COP87L88EB COP87L89EB COP87L88RB COP87L89RB Memory (bytes) 16k OTP EPROM 16k OTP EPROM 32k OTP EPROM 32k OTP EPROM Features include an 8-bit memory mapped architecture, 10 MHz CKI (-XE = crystal oscillator) with 1µs instruction cycle, two multi-function 16-bit timer/counters, WATCHDOG and clock monitor, idle timer, CAN 2.0B (passive) interface, MICROWIRE/PLUSTM serial I/O, SPI master/slave interface, fully buffered USART, 8 bit A/D with 8 channels, two power saving HALT/IDLE modes, MIWU, software selectable I/O options, low EMI 4.5V to 5.5V operation, program code security, and 44/68 pin packages.
