COP87L88GD/RD Family
8-Bit CMOS OTP Microcontrollers with 16k or 32k
Memory and 8-Channel A/D with Prescaler
General Description
The COP87L88GD/RD OTP (One Time Programmable)
Family microcontrollers are highly integratet COP8™ Fea-
ture core devices with 16k or 32k memory and advanced
features including an A/D Converter. These multi-chip CMOS
devices are suited for applications requiring a full featured
controller with an 8-bit A/D converter, and as pre-production
devices for a masked ROM design. Pin and software com-
patible 16k ROM versions are available (COP888GD), as
well as a range of COP8 software and hardware develop-
ment tools.
Family features include an 8-bit memory mapped architec-
ture, 10 MHz CKI (-XE = crystal oscillator) with 1µs instruc-
tion cycle, three multi-function 16-bit timer/counters,
MICROWIRE/PLUS™ serial I/O, one 8-bit/8-channel A/D
converter with prescaler and both differential and single
ended modes, two power saving HALT/IDLE modes, MIWU,
idle timer, high current outputs, software selectable I/O op-
tions, WATCHDOG™ timer and Clock Monitor, 2.7V to 5.5V
operation, program code security, and 44 pin package.
