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 Program-
mable) microcontrollers are highly integrated COP8™ Fea-
ture 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 compat-
ible 8k ROM versions (COP888EK) are available for use with
a range of COP8 software and hardware development tools.
Family features include an 8-bit memory mapped architec-
ture, 10 MHz CKI (-XE = crystal oscillator) with 1 µs instruc-
tion cycle, three multi-function 16-bit timer/counters with
PWM, MICROWIRE/PLUS™ serial I/O, one analog com-
parator with seven input multiplexor, an analog current
source and V_CC/2 reference, two power saving HALT/IDLE
modes, idle timer, MIWU, high current outputs, software se-
lectable I/O options, WATCHDOG™ timer and Clock Monitor,
2.7V to 5.5V operation and 28/40/44 pin packages.
