None of the PICs have a built-in RS485 transceiver. Any PIC with a UART will work with RS485 with an external transceiver.

RS485, RS422, RS232, and variants use a common serialization protocol that is supported by all PICs with UARTS (basic and enhanced). What differentiates these protocols is the line driver or transceiver connected to the UARTs pins of the PIC. Embedding the transceiver in the PIC is not commercially very attractive as it limits the addressable market of the PIC.
