A design and usage method based on custom pins of asic main control chip

Abstract

The invention discloses a design and use method based on customizing pins of an ASIC main control chip, including an embedded memory chip, and the embedded memory chip includes an ASIC main control chip, a flash memory chip and a substrate; the customizing pins of the ASIC main control chip Method: S1, design all possible functional modules; S2, define the number of pins of the ASIC main control chip according to the number of pad pins; S3, add an OTP unit inside the ASIC main control chip; use method of the ASIC main control chip: Q1 ,Design the substrate to ensure that the gold wire connection between the ASIC main control chip and the pad pins of the flash memory chip does not cross; Q2, multiplex the pad pins of the ASIC main control chip; Q3, the PC-side tool automatically scans the OTP unit; Q4 , to detect whether there is data in the OTP unit; Q5, if yes, use the ASIC main control chip normally; Q6, if not, customize the pad pin and write it into the OTP unit; then perform step Q5; a chip can be configured according to different purposes Proprietary ASIC chips can achieve functions and effects that require multiple different ASIC chips.

Description

technical field [0001] The invention relates to the field of semiconductor chips, in particular to a design and use method based on customizing pins of an ASIC main control chip. Background technique [0002] For the traditional ASIC main control chip, because all chip pin functions have been pre-defined and cannot be changed when the chip is taped out, for flash memory chips from different manufacturers, in order not to cross the gold wires, they can only be replaced continuously The underlying substrate design sometimes even requires dozens of different substrates to be kept on hand, which not only wastes resources, increases design complexity, but also greatly affects the customer's new product launch time and delivery date. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a design and use method based on the customization of ASIC main control chip pins. [0004] In order to achieve the a...
