PIC MARKINGS

Example 1: 16C54XX, where XX can be JW, RC, LP etc.
The 'C' means it is a one time programmable (OTP) device (unless the chip had a window in the top, see below).
Later chips with 'F' instead of the 'C', like the 16F84, were flash memory devices that allowed being programmed again and again.
16C54JW = windowed device (can be errased using a UV light)
16C54RC = One Time Programmable (OTP) = Resistor Capacitor oscillator
16C54LP = OTP, Low Power (e.g. 32kHz)
16C54XT = OTP, crystal or ceramic resonator oscillator (e.g. 4 MHz)
16C54HS = OTP, high speed oscillator (e.g. 20 MHz)

Example 2: PIC16F877A-20I/P
'PIC16F877' is the particular chip number / type
'A' is the revision version (i.e. an updated version).
The numbers '20' is the maximum frequency / speed in this case 20MHz.
The letters I/P at the end are i) the temperature range designations and ii) the package type:
For the temperature range designation:
C = normal: 0 to +70 C
I = industrial: -40 to + 85 C
E = extended: -40 to + 125 C
For the package type:
P = plastic and SO = surface mount

So a PIC16F877A-20I/P = is the latest (Revision A) version of the PIC16F877 chip which is a flash memory 20MHz industrial temperature range device in a plastic package.
Note: the A version of the 16F877 has Comparators and Comparator Voltage Reference modules that the PIC16F877 did not have (the older PIC16F877 is no longer avaliable).
