Description
The SN8P2501BS is an electronic component model in the IC Chips category. It offers various features such as memory configuration, I/O pin configuration, 3-level LVD, powerful instructions, and more. It has 1K * 16 bits OTP ROM size and 48 * 8 bits RAM size. The I/O pins include bi-directional, input only, programmable open-drain, wakeup, and pull-up resisters. The external interrupt trigger edge is controlled by the PEDGE register. It also has a 3-level LVD, reset system, power monitor, and powerful instructions. The SN8P2501BS has three interrupt sources including one internal interrupt (T0, TC0) and one external interrupt (INT0). It features two 8-bit Timer/Counters (T0, TC0) and an on-chip watchdog timer. It supports both external high clock (RC type up to 10 MHz, Crystal type up to 16 MHz) and internal high clock (16 MHz RC type, limited to Fcpu is limited to Fosc/4~Fosc/16). The operating modes include normal mode, slow mode, sleep mode, and green mode. The SN8P2501BS comes in PDIP 14 pins, SOP 14 pins, and SSOP 16 pins package options.
