Note 2: Absolute maximum ratings indicate limits beyond which damage to
the device may occur. DC and AC electrical specifications are not ensured
when operating the device at absolute maximum ratings.DescriptionThe COP8FGx5 Family ROM based microcontrollers are highly integrated COP8™ Feature core devices with 8k to 32k memory and advanced features including Analog comparators, and zero external components. These single-chip CMOS devices are suited for more complex applications requiring a full featured controller with larger memory, low EMI, two comparators, and a full-duplex USART. COP8FGx7 devices are 100% form-fit-function compatible 8k or 32k OTP (One Time Programmable) versions for use in production or development.
Erasable windowed versions are available for use with a range of COP8 software and hardware development tools. COP8FGx5 Family features include an 8-bit memory mapped architecture, 15 MHz CKI with 0.67 s instruction cycle, 14 interrupts, three multi-function 16-bit timer/counters with PWM, full duplex USART, MICROWIRE/PLUS™, two analog comparators, two power saving HALT/IDLE modes, MIWU, idle timer, on-chip R/C oscillator, high current outputs, user selectable options (WATCHDOG™, 4 clock/oscillator modes, power-on-reset), 4.5V to 5.5V operation, program code security, and 28/40/44 pin packages.
