.. COP87L88EK/RK Family, 8-Bit CMOS OTP Microcontrollers with 8k or 32k Memory, parator, and Single-slope A/D Capability September 1999 COP87L88EK/RK Family 8-Bit CMOS OTP Microcontrollers with 8k or 32k Memory, parator, and Single-slope A/D Capability General Description The COP87L88EK/RK Family OTP (One Time Programmable) microcontrollers are highly integrated COP8™ Feature core devices with 16k or 32k memory and advanced Features including a Multi-Input parator 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 parator, current source, and voltage reference, and as pre-production devices for a masked ROM design. Lower cost pin and software patible 8k ROM versions (COP888EK) are available for use with a range of COP8 software and hardware development tools.
