Abstract

The invention provides a chip IO data processing method. a chip comprises a UART mode and an SPI mode. the processing method comprises the steps that when IO data are received, whether the IO data comprise preset specific data or not is judged; If yes, the chip maintains the preset mode unchanged and processes the IO data; Wherein the preset mode is any one of the UART mode and the SPI mode; And if not, the chip is switched from the preset mode to another mode to process the IO data. The UART module and the SPI module are respectively arranged in the chip, and the corresponding mode is identified according to the received IO data after the chip is powered on, so that two chips with different communication interfaces are not needed, the current market demand is more easily met, the inventory management of the metering chip is facilitated, and the stocking cost and the management cost are reduced. The invention also provides a chip which has the above beneficial effects.

Description

technical field [0001] The present application relates to the field of metering chips, in particular to a chip IO data processing method and a chip. Background technique [0002] At present, some power metering chips (non-SoC) mainly have the following two communication interfaces, UART and SPI. Design a new generation of energy metering chip, hoping to support UART and SPI at the same time, so that the chip can be used in a wider range and has a stronger substitution. [0003] Technical background: At present, the measurement chips on the market have SPI interface and UART interface, which cannot be unified. Chip manufacturers generally design chips for these two interfaces separately to meet different market demands. Now the tape-out cost is very high. If two chips with different communication interfaces are designed, the tape-out cost will be doubled directly. The cost of post-ATE testing, warehouse stocking, etc. will be doubled directly.
