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 ±4ºC.
To meet the demand for compactness, the IC comes in the World’s smallest and flattest 16-pin package (US16).

Description of Operation
2
Operation of E PROM read/write OP codes
The operations listed below in the Operation mode selection table are performed using the five pins V.P, W/R,
STB, CK and DIN.
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.

1. 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.
During a write, DOUT is High-Impedance.

7. 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.)

XOcont Output Operation
XOcont is the output pin used to output temperature compensation data (XOcont data) corresponding to the
output from the built-in temperature sensor. Data corresponding to each 1°C 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 25°C 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.

3. XOcont data
The XOcont data is stored at addresses 10H~6FH of the E2PROM and is used as compensation data
corresponding to every 1°C increment in the ambient temperature range -22°C~73°C.
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 -22°C or above
73°C), the compensation value for the table’s minimum or maximum temperature (-22°C or 73°C) is
output.

Temperature Sensor
The IC incorporates a temperature sensor which can detect temperatures with an accuracy of 1°C. The sum of
the output from the temperature sensor (after conversion to a digital value) and the 25°C 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 25°C 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 25°°C temperature sensor compensation data
If the ambient temperature is 25°C, the compensation data can be calculated as follows:
25°C temperature sensor compensation data = 3FH - temperature data before compensation
If the ambient temperature is not 25°C, add the difference between the ambient temperature and 25°C
to the result of the above calculation.
The following table shows 25°C temperature sensor compensation values corresponding to the ambient
temperature and the raw temperature data
