For example, PICs in the baseline (PIC12) and mid-range (PIC16) families have program memory addressable in the same wordsize as the instruction width, i.e. 12 or 14 bits respectively. In contrast, in the PIC18 series, the program memory is addressed in 8-bit increments (bytes), which differs from the instruction width of 16 bits.
Many analog to digital converters (ADCs) have a 12-bit resolution. Some PIC microcontrollers use a 12-bit instruction word but handle only 8-bit data. 12 binary digits, or 3 nibbles (a 'tribble'), have 4096 (10000 octal, 1000 hexadecimal) distinct combinations. Hence, a microprocessor with 12-bit memory addresses can directly access 4096 words ...
8-bit (8-bit data bus) PICmicro, with a single accumulator (8 bits): PIC10 and PIC12: 12-bit instruction words; PIC16 series: 14-bit instruction words, one address pointer ("indirect register pair") PIC16F628 (Replacement for very popular but discontinued PIC16F84) – PIC16F84A is still in production as of April 8, 2022.

The low-cost, low pin count PIC12LF1552 is Microchip's smallest (2x3 mm UDFN package) and lowest-cost PIC ® MCU with hardware I 2 C™ support, and includes a four channel 10-bit Analog-to ...
The H08A has a smaller 14-bit ROM space and 11-bit RAM space (vs. up to 20 and 12 bits on the PIC18), but it is not clear if this is an architectural limit or just that of current products. The H08A is missing the PIC18 PUSH , [ 31 ] DAW , TBLWR , CALLW , RESET , MOVF , SUBFWB , and NEGF instructions.
Multiple base registers could be used, for code or for data. Such instructions require less memory because they do not have to hold a full 24, 31, 32, or 64 bit address (4 or 8 bytes), but instead a base register number (encoded in 4 bits) and a 12–bit address offset (encoded in 12 bits), requiring only two bytes.
The ICD 2 supports most PIC and dsPIC devices within the PIC10, PIC12, PIC16, PIC18, dsPIC, rfPIC and PIC32 families, [4] and supports full speed execution, or single step interactive debugging. [3] At breakpoints, data and program memory can be read and modified using the MPLAB IDE. [2] The ICD 2 firmware is field upgradeable using the MPLAB ...
Microsoft shares are up around 12% over the last 12 months, lagging the broader S&P 500 , which has risen 26% during the period. Amazon and Google shares are up 52% and 35%, respectively, while ...
