September 1999
COP87L88EK/RK Family 8-Bit CMOS OTP Microcontrollers with 8k or 32k Memory, Comparator, and Single-slope A/D Capability
General Description
The COP87L88EK/RK Family OTP (One Time Programmable) microcontrollers are highly integrated COP8TM Feature core devices with 16k or 32k memory and advanced features including a Multi-Input Comparator and Single-slope A/D capability. These multi-chip CMOS devices are suited for applications requiring a full featured, low EMI controller with an analog comparator, current source, and voltage reference, and as pre-production devices for a masked ROM design. Lower cost pin and software compatible 8k ROM versions (COP888EK) are available for use with a range of COP8 software and hardware development tools. Device COP87L84EK COP87L88EK COP87L84RK COP87L88RK Memory (bytes) 16k OTP EPROM 16k OTP EPROM 32k OTP EPROM 32k OTP EPROM RAM (bytes) 256 256 256 256 Family features include an 8-bit memory mapped architecture, 10 MHz CKI (-XE = crystal oscillator) with 1 µs instruction cycle, three multi-function 16-bit timer/counters with PWM, MICROWIRE/PLUSTM serial I/O, one analog comparator with seven input multiplexor, an analog current source and VCC/2 reference, two power saving HALT/IDLE modes, idle timer, MIWU, high current outputs, software selectable I/O options, WATCHDOGTM timer and Clock Monitor, 2.7V to 5.5V operation and 28/40/44 pin packages.
