Embodiment Construction

[0015] refer to figure 1 , figure 1 A block schematic diagram of a chip 10 according to some embodiments is shown. The chip 10 includes a power pin 12 , a ground pin 14 , a plurality of input and output pins 20 , a readable and writable memory 30 , a switching circuit 40 , and a control circuit 50 . The input and output pins 20 include a plurality of mapping pins 22A˜ 22D and a control pin 24 . The readable and writable memory 30 includes a frequency port 32 , a plurality of input and output ports 34A˜ 34B, and an enable port 36 . The control circuit 50 activates or deactivates the switching circuit 40 according to the control pin 24 . When the switching circuit 40 is activated, the switching circuit 40 electrically connects the frequency port 32 , the input / output ports 34A- 34B, and the enabling port 36 to the mapping pins 22A- 22D respectively.

[0016] Therefore, the burning device 80 controls the pin 24 to make the control circuit 50 actuate the switching circuit 40. ...

Abstract

A chip with a memory comprises a power supply pin, a grounding pin, a plurality of input and output pins, a read-write memory, a switching circuit and a control circuit. The input / output pins comprise a plurality of mapping pins and a control pin. The read-write memory comprises a frequency port, a plurality of input / output ports and an enabling port. The control circuit selectively actuates or does not actuate the switching circuit according to the control pin, and when the switching circuit is actuated, the switching circuit electrically connects the frequency port, the input / output port and the enabling port to the mapping pin.

Description

technical field [0001] The invention relates to a chip, in particular to a chip with memory. Background technique [0002] A chip is an integrated circuit designed to perform specific or general functions. The chip contains control circuits and memory. In addition to providing memory for chip operation, part of the chip memory stores firmware (Firmware), which is the basic driver of the chip. The chip executes the functions of the chip through its firmware. In addition, the device connected to the chip can The type and functionality of the chip can be known from the firmware. [0003] In response to customization or different application situations, there is a need to update the firmware of the chip, and the firmware update is performed through the communication interface of the chip. However, different chips have different communication interfaces, such as I2C, SMBus (System Management Bus), Universal Serial Bus (USB, Universal Serial Bus), serial ports, etc. In additio...
