A programmer (hardware), device programmer, chip programmer, device burner,[1]:364 or PROM writer[2] is a piece of electronic equipment that arrange written software to configure programmable non-volatile integrated circuits, called programmable devices.[3]:3 The target devices include; PROM, EPROM, EEPROM, Flash memory, eMMC, MRAM, FeRAM, NVRAM, PLD, PLA, PAL, GAL, CPLD, FPGA, and MCU. These are terminologies in the field of computer hardware.

FunctionEdit

 
JTAG Connector-based
On-Board Programmer
for AVR microcontroller
with USB Port interface

Programmer hardware has two variants. One is configuring the target device itself with a socket on the programmer. Another is configuring the device on a printed circuit board.

In the former case, the target device is inserted into a socket (usually ZIF) on top of the programmer.[4]:642, pdf15 If the device is not a standard DIP packaging, a plug-in adapter board, which converts the footprint with another socket, is used.[5]:58

In the latter case, device programmer is directly connected to the printed circuit board by a connector, usually with a cable. This way is called on-board programming, in-circuit programming, or in-system programming.[6][7][8]

Afterwards the data is transferred from the programmer into the device by applying signals through the connecting pins. Some devices have a serial interface[9]:232, pdf3 for receiving the programming data (including JTAG interface).[4]:642, pdf15 Other devices require the data on parallel pins, followed by a programming pulse with a higher voltage for programming the data into the device.[10]:125

Usually device programmers are connected to a personal computer through a parallel port,[1]:364USB port,[11] or LAN interface.[12] A software program on the computer then transfers the data to the programmer,[1]:364[13]:430 selects the device and interface type, and starts the programming process to read/ write/ erase/ blank the data inside the device.[14][15]

There are four general types of device programmers:

1) Gang programmers (multi-programming sites, having a set of sockets)[16] for mass production.[4]:642, pdf15
2) Development programmers (usually single-programming site) for development and small-series production.[17]
3) Pocket programmers for development and field service.[17][18]
4) Specialized programmers for certain circuit types only, such as FPGA,[19] microcontroller,[4]:642, pdf15 and EEPROM programmers.[14]

Flash memory Programmer

Regarding old PROM programmers, as the many programmable devices have different voltage requirements, every pin driver must be able to apply different voltages in a range of 0–25 Volts.[20]:651[21]:40 But according to the progress of memory device technology, recent flash memory programmers do not need high voltages.[22][23]

In the early days of computing, booting mechanism was a mechanical devices usually consisted of switches and LEDs. It means the programmer was not an equipment but a human, who entered machine codes one by one, by setting the switches in a series of "on" and "off" positions. These positions of switches corresponded to the machine codes, similar to today's assembly language.[24]:261–262[25][26] Nowadays, EEPROMs are used for bootstrapping mechanism as BIOS, and no need to operate mechanical switches for programming.[27]:45
