【正文】 傳感器 在人類的生活環(huán)境中，溫度扮演著極其重要的角色。 piece inside oscillator and clock circuit Tube feet explains: VCC: power supply voltage. GND: grounded. P0 Mouth: P0 mouth a eight leak level twoway I/O mouth open, every foot can absorb 8TTL gate current. When the pipe mouth P0 feet first write 1, defined as high resistance input. 第 4 頁 P0 can be used for external program data storage, it can be defined as the eighth data/address. In FIASH programming, P0 mouth as the sourcecode input port, when FIASH check, the sourcecode P0 output, when P0 external must be pulled. P1 mouth: mouth is an internal P1 provide pullup resistors 8bit twoway I/O mouth, P1 mouth buffer can receive 4TTL gate current output. P1 mouth tube feet, was then write 1 for high, pull up inside can be used as input, P1 mouth be external pull down for low electricity at ordinary times, will output current, this is due to internal pull up sake. In FLASH programming and calibration, P1 mouth as eighth address to receive. P2 mouth: for an internal P2 mouth on the 8bit pullup resistors twoway I/O port, P2 mouth to receive, the output buffer 4 TTL gate current, when P2 mouth is written 1, its tube feet are internal pullup resistors, and push as input. And so as the input, P2 mouth feet are external down tube, will output current. This is due to internal pull up sake. P2 mouth when used external program memory or 16 address external data memory access, P2 mouth high output address eight. In a given address 1, it using internal and external 8 address advantage, when for reading and writing data memory, P2 when the special function registers mouth output of content. P2 mouth in FLASH programming and the calibration eight address when receiving high signal and control signals. P3 mouth: P3 mouth pipe is 8 feet with internal pullup resistors twoway I/O port, may receive four TTL gate current out put. When P3 mouth writing 1, they are internal and high level, and used as input. As input, due to external dropdown for low level, P3 mouth will output current (ILL) this is due to pull up39。 programmable serial channels two 16 timer 128 x 8 bits internal RAM the static job: 0Hz 24MHz life: 1000 write/wipe cycle and MCS 51 patible Typical products have AD590 AD592, TMP17, LM135, integrated temperature controller. Analog integrated temperature controller mainly include temperature control switch, programmable temperature controller, a typical product have LM56, AD22105 and MAX6509. Some increase strength type integrated temperature controller (for example TC652/653) also contains the A/D converter and cure good sequence, this process with the intelligent temperature sensor some similarities. But it is not its system, work by micro processing d
