COP87L88CL
8-Bit One-Time Programmable (OTP) Microcontroller
General Description
COP8SG devices are
form-fit-function compatible supersets of the COP87L88CL
Family devices, and are replacements for these in new
designs, and design upgrades with minimum effort.
The COP87L88CL OTP microcontrollers are larger memory
(16k), highly integrated COP8
TM
Feature core devices, with
advanced features. These multi-chip CMOS devices are
suited for applications requiring a full featured controller with
a high I/O pincount, and as pre-production devices for a
masked ROM design. Lower cost pin and software compat-
ible 4k ROM versions are available (COP888CL/988CL).
Family features include an 8-bit memory mapped architec-
ture, 10MHz CKI with 1 s instruction cycle, two multi-
function 16-bit timer/counters, MICROWIRE/PLUS
TM
serial
I/O, two power saving HALT/IDLE modes, idle timer, MIWU,
high current outputs, software selectable I/O options,
WATCHDOG
TM
timer and Clock Monitor, 2.7v-5.5v opera-
tion, program code security, and 28/40/44 pin packages.
