The internal hardware of the HP-12C changed again in 2015, when the design switched to use an Atmel ATSAM4LC2CA-AU processor with ARM Cortex-M4 core. [2] The calculator's part number and physical appearance didn't change except for a "Rev 2" plate on the bottom side. [2] It continues to use two parallel CR2032 cells. [2] The firmware reports a 2015 build date. [2] Serial numbers starting with "PHA", "9CJ", "7CD", or "3CD" rule out the older model variant. [2] The 2×3-pin flash port now uses the USB protocol instead of a TTL serial protocol; [2] in addition to this, the calculator's circuit board features an unpopulated mount for a Micro-USB connector.

The HP-10C is the last and lowest-featured calculator in this line, even though its number would suggest an earlier origin. The 10C was a basic scientific programmable calculator. While a useful general purpose RPN calculator, the HP-11C offered twice as much for only a slight increase in price. Designed to be an introductory calculator, it was still costly compared to the competition, and many looking at an HP would just step up to the better HP-11C. Poor sales led to a very short market life, making it one of the most difficult of the series to find today. a b Without DSZ/DSE (Decrement and Skip) and ISZ/ISG (Increment and Skip) writing loops is difficult. The HP-12C is one of only four calculators permissible in the Chartered Financial Analyst exams, the others being its sister, the HP12c Platinum, and the Texas Instruments BA II Plus and BA II Plus Professional. The first release of the 12c Platinum used a faster processor than the revision of the original HP-12C which was available at that time. (However, the subsequent revisions of the original 12C which switched to ARM-based processors have reversed that speed gap.) It was equipped with a Sunplus SPLB20D2 [1] [18] with a 6502 core, larger memory (for up to 30 CFj registers [17] and 400 program steps) and more built-in functions. It allows input to be entered in algebraic mode as well as in 4-level classical RPN. The calculator's particular implementation of RPN exhibits an unusual behaviour of the CHS key different from that of the 12C and other classical RPN calculators. [19]a b Hidalgo, Jordi (2004-06-09).

The calculator was introduced in 2003, is visibly distinguished by its silver-colored upper half as opposed to the gold-colored plate on the original 12c. There are six variants of the HP12c Platinum (including two special issues). The HP-16C is a computer programmer's calculator, designed to assist in debugging. It can display numbers in hexadecimal, decimal, octal and binary, and convert numbers from one base to another. A number of specialized functions are provided to assist the programmer, including left- and right-shifting, masking, and bitwise logical operations. HP has (as of 2015) never made another programmer's calculator, but has incorporated the 16C's functions in later calculator models. In 2012, SwissMicros (aka RPN-Calc) introduced a miniature clone named DM-12CC approximating the size of an ID-1 credit card (88mm× 59mm× 7mm). It closely emulates the functionality of the original HP-12C by running the original ROM image in an emulator on an ARM Cortex-M0-based NXP LPC1114 processor. Newer DM12 models since 2013 feature a better keyboard and more RAM ( LPC1115). A DM12 Silver Edition in a titanium case is available as well. [26]

The available programming features differentiate between the various HP Voyager series calculator systems. The HP calculators Voyager series consisted of five models, some of which were manufactured in several variants (with years of production):
