Problems solved by technology

However, it is very difficult to implement power management on the logic chip in the smart card, and a new solution must be found to realize the power management inside the smart card
[0009] In order to enhance their absolute dominant position in the industry chain, operators continue to develop their own value-added services, and try to control mobile phone manufacturers and businesses through various means. However, due to the large number of mobile phone manufacturers and the unique sales model of mobile phones, operators Unable to build and unify its business well on the mobile platform, so this attempt has had little success

Embodiment Construction

[0058] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0059] The invention includes a powerful and complete hardware platform and an efficient and flexible software system. The hardware platform implements basic communication and computing functions, and on this basis, the software system implements and completes complex services / applications.

[0060] The hardware platform of the present invention includes three parts: a microcontroller unit, a power management unit and an extended memory unit. The functions and structures of these parts can be flexibly combined as required. Either single-chip packaging can be adopted, and only the microcontroller unit or all three parts of the unit can be packaged into an independent SoC (System on Chip, system chip) chip for use; multi-chip methods can also be used to separate all three parts For packaging, each part is packaged into a chip, and then multiple...

Abstract

An intelligent card supporting high performance calculation and large-capacity storage as well as high speed transmission is prepared for connecting power supply management unit with two base pins and connecting microcontroller unit to the other six base pins according to base pin code defined by ISO / IEC 7816-3 protocol, connecting expansion storage unit separately to power supply management unit and microcontroller unit.

Description

technical field [0001] The invention belongs to the field of smart card / integrated circuit chip design and application, in particular to the design and application of a smart card with high computing performance, super large storage capacity and high-speed transmission interface. Background technique [0002] A smart card, also called an IC card, is a card that has an integrated circuit chip with storage, encryption and data processing capabilities embedded in a plastic substrate. Smart cards are divided according to the embedded chips, and can be divided into two categories: memory cards and microprocessor cards. The memory card uses the memory chip as the card core, which is only composed of "hardware", including data memory and safety logic control, etc.; the microprocessor card uses the microprocessor chip as the card core, which is composed of hardware and software. The hardware part usually includes a hardware microprocessor for calculation and control, random access ...
