MCP795xx / MCP795Wxx RTCCs

Microchip Technology MCP795xx / MCP795Wxx Real-Time Clock Calendar ICs (RTCCs) are 10-pin devices that provide accurate timekeeping over a wide temperature range, power-failure monitoring, and on-chip nonvolatile memory. These small-package devices offer many of the same features as the larger 14-pin MCP795Wxx family.
