C8051F326/7
1.6.
C8051F326/7 devices include 15 I/O pins (one byte-wide Port, one 6-bit-wide and one 1-bit-wide Port).
The C8051F326/7 Ports behave like typical 8051 Ports with a few enhancements. Each Port pin may be
configured as a digital input or output pin. Pins selected as digital outputs may additionally be configured
for push-pull or open-drain output. The “weak pullups” that are fixed on typical 8051 devices may be glob-
ally disabled, providing power savings capabilities.
1.7.
The C8051F326/7 Family includes a full-duplex UART with enhanced baud rate configuration. The serial
interface is fully implemented in hardware and makes extensive use of the CIP-51's interrupts, thus requir-
ing very little CPU intervention.
