absolute maximum ratings.DescriptionThe COP87L88EB/RB Family OTP (One Time programmable) microcontrollers are highly integrated COP8™ 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.
Features of COP87L88EB include an 8-bit memory mapped architecture, 10 MHz CKI (-XE = crystal oscillator) with 1s instruction cycle, two multi-function 16-bit timer/counters, WATCHDOG and clock monitor, idle timer, CAN 2.0B (passive) interface, MICROWIRE/PLUS™ 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.
Note: A companion device with CAN interface, less I/O and memory, A/D, and PWM timer is the COP87L84BC.
