Embodiment Construction

[0016] Such as figure 1 As shown, the programming tool of the present invention is used to adjust the voltage output to the four signal pins TEST, TEST2, FEED and IO of the RE46C190 chip according to the data transmission status of the RE46C190 chip. A preferred embodiment of the RE46C190 chip programming tool includes a RE46C190 chip, a control module and a switch module.

[0017] RE46C190 chip includes TEST, TEST2, FEED and IO four signal pins, V SS , V BAS and V DD Three power pins.

[0018] The control chip includes five signal pins IN1, IN2, IN3, IN4 and IN5. The signal pins IN4 and IN5 of the control chip are respectively connected to the signal pins TEST2 and IO of the RE46C190 chip; the signal pins IN1, IN2 and IN3 of the control chip They are respectively connected to the signal pins TEST and FEED of the RE46C190 chip through the switch module. When the control chip reads and writes data to the RE46C190 chip, the five signal pins of the control chip IN1, IN2, IN3...

Abstract

A chip programming tool is used for adjusting voltages output to TEST, TEST2, FEED and IO signal pins of an RE46C190 chip according to a data transmission state of the RE46C190 chip. The chip programming tool comprises the RE46C190 chip, a control module and a switch module; when the control chip is used for carrying out data reading or writing on the RE46C190 chip, the IN1, IN2, IN3, IN4 and IN5 signal pins of the control chip are used for outputting high and low level signals to the TEST, TEST2, FEED and IO signal pins of the RE46C190 chip; and when the control chip is not used for carrying out data reading or writing on the RE46C190 chip, the IN1, IN2, IN3, IN4 and IN5 signal pins of the control chip are not used for outputting the signals.

Description

technical field [0001] The invention belongs to the technical field of electronic control, and in particular relates to a chip programming tool. Background technique [0002] RE46C190 is a low power consumption, low voltage CMOS photoelectric smoke detector IC. Features: Operates on two AA batteries; internal power-on reset; low quiescent current; local alarm memory; 9-minute timer for sensitivity control; short or continuous beep mode; internal low battery and chamber test; battery The low battery set point is 2%. This circuit provides all the necessary functions of a photoelectric smoke detector using a minimum number of external components. The device uses an internal oscillator to strobe the power supply to the smoke detection circuit every 10 seconds to keep standby current to a minimum. When smoke is detected, the device increases the detection rate to verify that an alarm condition exists. The device provides a high-gain mode for key chamber testing. During the p...
