Note 1: 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.DescriptionNote: COP8SAx devices are instruction set and pin compatible supersets of the COP800 Family devices, and are replacements for these in new designs when possible.
The COPSAx Rom based and OTP microcontrollers are highly integrated COP8™ feature core devices, with 1k to 4k memory and advanced features including low EMI. These single-chip CMOS devices COP8SAx are suited for low cost applications requiring a full featured controller, low EMI, and POR. 100% form-fit-function compatible OTP versions are available with 1k, 2k, and 4k memory, and in a variety of packagesincluding 28-pin CSP. Erasable windowed versions are available for use with a range of COP8 software and hardware development tools.
COP8SAx Family features include an 8-bit memory mapped architecture, 10 MHz CKI with 1 s instruction cycle, one multifunction 16-bit timer/counter with PWM output, MICROWIRE/PLUS™ serial I/O, two power saving HALT/ IDLE modes, MIWU, idle timer, on-chip R/C oscillator, 12 high current outputs, user selectable options (WATCHDOG ™, 4 clock/oscillator modes, power-on-reset), low EMI 2.7V to 5.5V operation, and 16/20/28/40/44 pin packages.
