[Answer] : PROM and the array is fixed, the chip area is large, the working speed is low, and it is generally used to make function tables, display decoding circuits and memory. The PLA output circuit is fixed, and the utilization rate of the door is low. The PAL output circuit has many structure forms, which can easily constitute various timing circuits, but the output mode cannot be reconfigured. The output circuit of GAL is set up with output macro unit OLMC, which can be configured by itself, and has strong functions and can be programmed many times.
Its output can be selectively held or hosted by a trigger. PAL device can be used by anti-fuse technology, EPROM technologyThe technique is realized by EEPROM. PLA (Programmable Logic Array) is more flexible, with programmable connections to and from the plane and or plane.
In practical applications, GAL devices have 100% compatibility with PAL device simulation, so GAL can almost completely replace PAL devices, and can replace most SSI and MSI digital integrated circuits, so it is widely used. The biggest difference between GAL and PAL is that GAL's output structure can be defined by the user and is a programmable output structure. Two basic GAL models GAL16V8 (GAL20V8 (24-pin) can replace ten PAL devices, so it is called pain programmable circuit.
The STC burner is mainly programmed through the UART interface, it is not a specialized burning device, so its function is limited, only support burning STC series MCU chips, for other types of chips, such as GAL16V8D, it is not applicable. GAComponents. It is an integrated block of logic gate circuit designed by users themselves, which can replace the logic circuit composed of 7CD4000 series and other arbitrary TTL.
2, GAL (Generic Array Logic) is a programmable logic device (PLD) that can be electrically erased, reprogrammable, and encrypted, launched by the United States Semiconductor company. GAL circuit can be repeatedly programmed, using electric erase technology, can be modified at any time, its internal has a special structure control word, so that it has fewer chip types and full functions.
3, [Answer] : GAL universal array logic device, it can be electrically erased, repeatable programming, output in the form of logic macro unit, free programming by the user flexibility, high degree of confidentiality.
4, GAL22V10D is a chip based on E2CMOS technology, which integrates advanced UltraMOS process, capable of providing a maximum transmission delay of 4 nanoseconds and 250 MHZ Fmax. Features of the chip include a maximum clock input-to-data output delay of 5 nanoseconds, as well as full functionality, fuse map, and parameters using a standard-compatible 22V10 deviceData compatibility.
5, the STC burner is a dedicated UART interface download line, not a burner in the strict sense, he can not burn other chips other than STCMCU, let alone GAL. GAL is a programmable logic chip, in general, find the original burning tool or find a third party burning tool.
6, GAL22V10D is the model GAL22V10D-10LJ memory chip. The gal22v10d has an Fmax of 250 MHZ, has a maximum clock input to data output of 5 nanoseconds, and a maximum of 4nsTransmission delay, is OTP single-chip one-time chip.
Generic Array Logic (GAL) is a programmable logic device (PLD) that can be electrically erased, reprogrammable, and encrypted, launched by Semiconductor. GAL circuit can be repeatedly programmed gal chip, the use of electric erase technology gal chip , can be modified at any time gal chip , its internal has a special structure control word, so that it is less chip type, full function.

Regarding the chip you mentioned, the screen print on it is "1812", which is most likely the model or identifier of the chip. However, it is difficult to determine the specific purpose of the chip from this information alone. It could be a power management chip, or it could be some other type of controller chip that manages data transfers or provides interface functions. If your tablet won't turn on and the chip is hot, it could mean a fault.
MCU refers to a complete computer system integrated on a chip. Although most of himThe functions are integrated on a small chip, but it has most of the components needed for a complete computer: CPU, memory, internal and external bus systems, and most of these days, external memory. It also integrates peripheral devices such as communication interface, timer and real-time clock.
