TMC332 DATA SHEET (V. 2.04 / November 9, 2009)
5
5 Pinning
A single package variant (BGA FG144, 0.5mm pitch) is available for the TMC332. For proper
operation, it is strongly recommended to connect all power and ground pins (3.3V, 1.5V, GND).

Description
low active reset input
clock input
low active enable input, nEN='1' disables all gate control signals equivalent to OVC
low active SPI chip select input of the TMC332 driven from µC
low active SPI chip select input driven from µC to select the TMC428
serial data clock input driven from µC
serial data input driven from µC
input driven by the SDO_C of the TMC428
serial data output to µC (from TMC332 or TMC428, depending on nSCS /
nSCS_428)
step pulse input (logical ored with internal STEP pulse via TMC428 SPI driver
chain)
direction input (logical ored with internal STEP pulse via TMC428 SPI driver chain)
low active SPI chip select input driven from TMC428 (driver by nSCS_S)
serial data clock input driven from TMC428 (driven by SCK_S)
serial data input driven from TMC428 (driven by SDO_S)
serial data output to TMC428 SDI_S or to next SPI driver within chain (SDI)
gate control high side, 0 : low active gate control / 1 : high active gate control
gate control low side, 0 : low active gate control / 1 : high active gate control
high side gate control outputs T1H, T2H, T3H, T4H on OVC condition
low side gate control outputs T1L, T2L, T3L, T4L on OVC condition
high active OVC input (from comparator output that is high on OVC condition)
low active OVC input (from comparator output that is low on OVC condition)
over current status ( 0 : no over current condition / 1 : over current condition)
direction of motion clockwise / counter clockwise, direction depends on motor
'0' : selects two phase stepper scheme '1' : selects three phase stepper scheme
