| TC7MTX01FK TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC TC7MTX01FK Digital temperature compensation IC Due to the demand for compactness and lower power dissipation, circuits for portable devices are being manufactured as individual chips. In particular, during the manufacture of modular devices comprised of several individual discrete devices, significant time and effort must be devoted to adjusting the temperature characteristic of each discrete device individually, In addition, the demand for low power consumption is increasing. In response to these requirements, Toshiba have developed the TC7MTX01FX, a digital temperature compensation IC. Toshiba have implemented this device completely in CMOS, obviating the need to use combinations of individual electronic components, such as thermistors and resistors, as was the case Weight: 0.02 g (typ.) previously. The new digital temperature compensation IC incorporates a temperature sensor, an E2PROM and a DA converter. The IC is accurate to within 4C. To meet the demand for compactness, the IC comes in the World's smallest and flattest 16-pin package (US16). Features * * Temperature compensation precision: 4C (in the range -20~70C) Analog output (XOcont): Outputs an analog voltage whose level corresponds to 1C increments in the above temperature range.

All operations modes other than Normal Operation Mode are triggered by 8-bit serial data input on DIN and CK on the rising edge of STB. The operation mode is determined by the combination of the W/R signal and the OP code.

E PROM Write Mode (V.P = 18 V, W/R = "H", DI1 = "H") Input of an OP code (DI1 = H, A6~A0 = address of word to be written) on DIN (while 18 V is applied to V.P, W/R = H and STB = H) writes data D0~D7 to the E2PROM at the timing shown below. Note that if D0~D7 are all High, a Byte Erase (all bits are set to H) is performed. The write starts on the falling edge of the 16th CK pulse and ends when STB goes Low.

Normal Operation Mode (STB = "L") While STB = L, all inputs on W/R, CK and DIN are invalid and the IC is in Normal Operation Mode (this is referred to as XOcont Output Control state). During Normal Operation Mode, the DOUT output level reflects the power-on reset status. (Output level is High during power-on reset and Low after release of power-on reset.) 6 2002-03-18 TC7MTX01FK E PROM Contents The E2PROM is organized as 8 bits x 124 words (= 992 bits) and its contents is as shown below.

Data corresponding to each 1C temperature increment is stored in the E2PROM. 1. Output at power-on At power-on, 1/2 x ref. voltage (80H) is output on XOcont. Delay time tpux, from power-on to start of output of 1/2 x ref. voltage, is 100 ms or less. 2. Output caused by trigger input The rising edge of the Trig.1 input triggers the built-in temperature sensor. The sum of the temperature sensor output and 25C temperature sensor compensation data (stored at address 0FH) is used as the XOcont data address. The XOcont data is converted to an analog voltage level and output on XOcont. The delay time txoc, from Trig.1 input to start of voltage output, is 500 ms or less.

XOcont data The XOcont data is stored at addresses 10H~6FH of the E2PROM and is used as compensation data corresponding to every 1C increment in the ambient temperature range -22C~73C. The voltage output on XOcont corresponds to the 8-bit data stored in the E2PROM (0 V for the value stored at address 00H; VRef for the value stored at address FFH). When the ambient temperature is outside the range of the E2PROM table (i.e. below -22C or above 73C), the compensation value for the table's minimum or maximum temperature (-22C or 73C) is output. 8 2002-03-18 TC7MTX01FK Temperature Sensor The IC incorporates a temperature sensor which can detect temperatures with an accuracy of 1C. The sum of the output from the temperature sensor (after conversion to a digital value) and the 25C temperature sensor compensation data (stored at address 0FH) is used as the E2PROM address of the compensation data. In Normal Operation Mode, the temperature sensor is inactive. The sensor is triggered by the rising edge of STB or by the Trig.1 input. On completion of operation, the sensor returns to its inactive state. The 25C temperature sensor compensation data can be written to address 0FH of the E2PROM as follows: 1. Measurement of ambient temperature and device temperature data (before compensation) * * The ambient temperature of the test environment is measured. Read the temperature data of TC7MTX01FK before compensation 2. Calculation of 25C temperature sensor compensation data * * If the ambient temperature is 25C, the compensation data can be calculated as follows: 25C temperature sensor compensation data = 3FH - temperature data before compensation If the ambient temperature is not 25C, add the difference between the ambient temperature and 25C to the result of the above calculation. The following table shows 25C temperature sensor compensation values corresponding to the ambient temperature and the raw temperature data 25C temperature sensor compensation values corresponding to the ambient temperature and the temperature data before compensation Temperature Data before Compensation (TC7MTX01FK) 82 81 80 7F 7E 7D 7C 7B 7A 79 78 77 76 75 74 73 72 71 70 6F 6E 6D 6C 6B 6A 69 BA BB BC BD BE BF C0 C1 C2 C3 C4 C5 C6 C7 C8 C9 CA CB CC CD CE CF D0 D1 D2 Ambient Temperature in Test Environment 21C 22C BA BB BC BD BE BF C0 C1 C2 C3 C4 C5 C6 C7 C8 C9 CA CB CC CD CE CF D0 D1 D2 D3 23C BB BC BD BE BF C0 C1 C2 C3 C4 C5 C6 C7 C8 C9 CA CB CC CD CE CF D0 D1 D2 D3 D4 24C BC BD BE BF C0 C1 C2 C3 C4 C5 C6 C7 C8 C9 CA CB CC CD CE CF D0 D1 D2 D3 D4 D5 25C BD BE BF C0 C1 C2 C3 C4 C5 C6 C7 C8 C9 CA CB CC CD CE CF D0 D1 D2 D3 D4 D5 D6 26C BE BF C0 C1 C2 C3 C4 C5 C6 C7 C8 C9 CA CB CC CD CE CF D0 D1 D2 D3 D4 D5 D6 D7 27C BF C0 C1 C2 C3 C4 C5 C6 C7 C8 C9 CA CB CC CD CE CF D0 D1 D2 D3 D4 D5 D6 D7 D8 28C C0 C1 C2 C3 C4 C5 C6 C7 C8 C9 CA CB CC CD CE CF D0 D1 D2 D3 D4 D5 D6 D7 D8 D9 29C C1 C2 C3 C4 C5 C6 C7 C8 C9 CA CB CC CD CE CF D0 D1 D2 D3 D4 D5 D6 D7 D8 D9 All values above are hexadecimal. 3.
