COP888xG/CS Family 8-Bit CMOS ROM Based Microcontrollers with 4k to 24k Memory, Comparators and USART
General Description
Note: COP8SG devices are form-fit-function compatible supersets of the COP888xG/CL/CS Family devices, and are replacements for these in new designs, and design upgrades with minimum effort. The COP888xG ROM based microcontrollers are highly integrated COP8TM Feature core devices with larger memory (4k to 24k) and advanced features including two Analog comparators. These single-chip CMOS devices are suited for more complex applications requiring a full featured controller with a range of memory sizes, low EMI (except EG), comparators, and a full-duplex USART. Pin and software compatible (different VCC range) 8k toor 32k OTP (One Time Device COP684CS COP884CS COP984CS COP688CS COP888CS COP988CS COP884CG COP888CG COP684EG COP884EG COP984EG COP688EG COP888EG COP988EG COP688GG COP888GG COP688HG COP888HG COP688KG COP888KG Memory (bytes) 4k ROM 4k ROM 4k ROM 4k ROM 4k ROM 4k ROM 4k ROM 4k ROM 4k ROM 4k ROM 4k ROM 8k ROM 8k ROM 8k ROM 16k ROM 16k ROM 20k ROM 20k ROM 24k ROM 24k ROM RAM (bytes) 192 192 192 192 192 192 128 128 256 256 256 256 256 256 512 512 512 512 512 512 I/O Pins 24 24 24 36/40 36/40 36/40 24 34/38 24 24 24 36/40 36/40 36/40 36/40 36/40 36/40 36/40 36/40 36/40 Programmable) versions are available (COP8SGx7 Family).
