Description
Technical field
The present invention relates to the configurable oscillatory circuit treatment circuit of a kind of power consumption and method.
Background technology
OTP(dynamic token product) before client uses, want complete design and production test.The low-power consumption requirement of design phase demand fulfillment dynamic token system.Test phase then needs to reduce testing cost.Dynamic token system needs through dependence tests such as the working procedure programming flow process of complexity and the performance tests of Related product when producing.Need in testing process to repeat token system power on and off, power at every turn need the MCU chip crystal oscillator starting of oscillation in system stablize after just send corresponding order by host computer and carry out follow-up test.
The shipment amount of dynamic token system is very large, the test link through complexity is needed in production run, and artificial and time cost is also progressively improving now, so in the multi-step production procedure of electronic product, the time shortening each production link is exactly the cost reducing product, this link of enterprise managing, except relying on optimum management link, also relies on the performance parameter of electronic product simultaneously.Such as: product needs constantly to power in test process, power-down operation, can shortening time of proper testing if arrive system from power on, namely can reduce the cost of test by reducing the corresponding test duration.
Existing OTP(dynamic token product) product is a kind of battery powered scrambler of super low-power consumption, intrasystem general MCU chip is responsible for the steering logic of disposal system.MCU chip comprises several module: CPU (central processing unit) below, Clock management module, reset administration module, memory cell, keystroke interface unit, segment encode screen display unit, real time clock unit, other Peripheral Interface unit such as timer, as shown in Figure 1.Dynamic token requires run for 5 years battery powered time.Token work is mainly divided into two class mode of operations: deep power down mode and operational mode.Token system is when deep sleep state, and power consumption is less than 0.8ua; Token system is when operation, and power consumption is less than 100ua; The power consumption consumed when token system deep-sleep mainly contains the vibration power consumption of 32K crystal oscillator, the power consumption of the wakeup logic consumption of MCU chip, the power consumption that the leakage current being in deep-sleep module consumes.
The electric power system of existing MCU chip and clock system are as shown in Figure 2, when token system penetration depth park mode, need the circuit of work: the wakeup logic (logical circuit comprises wakeup logic and other operating circuit logics) in low-speed oscillation circuit, voltage conversion circuit, logical circuit.Voltage conversion circuit and low-speed oscillation circuit are the keys of system power dissipation under decision park mode.Voltage conversion circuit realizes voltage transitions while of needing circuit itself to leak electricity low efficiently; Low-speed oscillation circuit needs under the prerequisite meeting industrial standard, realize low-power consumption vibration.The oscillatory circuit of low-speed oscillation circuit to be frequency be 32K, because token system requires low power operation, the power consumption of 32K oscillatory circuit must accomplish enough low low power operations that could support whole token system.System electrification, 32K vibration get up after system program could normal run, so the working time (arriving the time that program normally can perform needs from power on) after the powering on of the starting of oscillation speed influential system of 32K oscillatory circuit.
Token is before user uses, and token manufacturer needs downloading-running program to the nonvolatile storage space of chip internal and carries out the dependence test of token system.Dynamic token system often needs to repeat to operate token system power on and off in the flow process of production test.The re-powering of each chip need 32K oscillator vibrates stablize after could perform relevant test operation.Fig. 3 is the basic operation process flow diagram of test link, and namely will maintain after sending reset command 3 seconds is to wait for 32K clock stable (the 32K clock driving force more weak time needing to wait for is longer).After each system electrification, host computer sends to first order of slave computer, need slave computer make system hold reset state 3 seconds by software control after slave computer first test command just sending parsing to give token system, as shown in Figure 4.Require that power consumption is less than 0.8ua under token system deep power down mode, namely require that MCU chip provides the oscillatory circuit of low-power consumption, the oscillatory circuit starting of oscillation of low-power consumption is slow.The token system integrating this type of MCU has test link in process of production, the node of test link needs to re-power system, re-power the starting of oscillation again of the low-power consumption oscillatory circuit of corresponding MCU at every turn, because the starting of oscillation of low-power consumption oscillatory circuit is slow, so first test command that after re-powering, host computer sends at every turn, be resolved to corresponding 2 orders in fact of final token system (to add before real order allow one period of reset time low-power consumption oscillatory circuit stable after the stable operation of token system ability).The time length of the reset command on token system in 2 orders directly affects final testing cost.
