The PIC18F4553 family of devices offers the advantages of all PIC18 microcontrollers – namely, high computational performance at an economical price – with the addition of high-endurance, Enhanced Flash program memory. In addition to these features, the PIC18F2553 family introduces design enhancements that make these microcontrollers a logical choice for many high-performance, power sensitive applications by IC code extraction.

· 12-Bit A/D Converter: The PIC18F2553 family implements a 12-bit A/D Converter. The A/D Converter incorporates programmable acquisition time. This allows for a channel to be selected and a conversion to be initiated, without waiting for a sampling period and thus, reducing code overhead.

The PIC18F2553 devices are available in 28-pin and 40/44-pin packages. Block diagrams for the two groups are shown in Figure 1-1 and Figure 1-2.

The devices are differentiated from each other in the following ways:

1. Flash program memory (24 Kbytes for PIC18FX458  devices,   32 Kbytes  for PIC18FX553).

2. A/D channels (10 for 28-pin devices, 13 for 40-pin and 44-pin devices).

3. I/O ports (3 bidirectional ports and 1 input only port on 28-pin devices, 5 bidirectional ports on 40-pin and 44-pin devices).

4. CCP and Enhanced CCP implementation (28-pin devices have two standard CCP modules, 40-pin and 44-pin devices have one standard CCP module and one ECCP module). Streaming Parallel Port (present only on 40/44-pin devices).

All other features for devices in this family are identical. These are summarized in Table 1-1. Members of the PIC18F4553 family are available as both standard and low-voltage devices. Standard devices with Enhanced Flash memory, designated with an “F” in the part number (such as PIC18F2553), accommodate an operating VDD range of 4.2V to 5.5V. Low-voltage parts, designated by “LF” (such as PIC18LF2553), function over an extended VDD range of 2.0V to 5.5V.
