7 / 53 page TMC260 and TMC261 DATASHEET (Rev. 2.05 / 2012-NOV-05) 7 www.trinamic.com Pin Number Type Function SDI 15 DI VIO SPI serial data input. (Scan test input in test mode.) SCK 16 DI VIO Serial clock input of SPI interface. (Scan test shift enable input in test mode.) GND 17, 39, 44 Digital and analog low power GND. CSN 18 DI VIO Chip select input for the SPI interface. (Active low.) ENN 19 DI VIO Power MOSFET enable input. All MOSFETs are switched off when disabled. (Active low.) CLK 21 DI VIO System clock input for all internal operations. Tie low to use the on-chip oscillator. A high signal disables the on-chip oscillator until power down. VHS 35 High-side supply voltage (motor supply voltage - 10V) VS 36 Motor supply voltage TST_ANA 37 AO VIO Reserved. Do not connect. SG_TST 38 DO VIO stallGuard2 output. Signals a motor stall. (Active high.) VCC_IO 40 Input/output supply voltage VIO for all digital pins. Tie to digital logic supply voltage. Operation is allowed in 3.3V and 5V systems. DIR 41 DI VIO Direction input. Sampled on an active edge of the STEP input to determine stepping direction. Sampling a low increases the microstep counter, while sampling a high decreases the counter. A 60-ns internal glitch filter rejects short pulses on this input. STEP 42 DI VIO Step input. Active edges can be rising or both rising and falling, as controlled by the DEDGE mode bit. A 60-ns internal glitch filter rejects short pulses on this input. TST_MODE 43 DI VIO Test mode input. Puts IC into test mode. Tie to GND for normal operation. |
