3.1 Power supply structure
3.1.1 Current Measurement Jumpers
Each power supply of the MCU is routed through a single Jumper before connecting it to the MCU. This makes
it possible to measure the current consumption of the MCU for each power supply domain in separate.
Table 3-1: Current measuements jumpers (excluding I/O ports supply)
AWO digital circuits via on-chip voltage regulator; nominal 3.3 V and 5 V
MainOsc and SubOsc; nominal 3.3 V and 5 V
Flash memory, nominal 3.3 V and 5 V ※1
ISO digital circuits, nominal 1.25 V
Zero point detection circuit; nominal 5 V
Reference voltage of Zero Point detection, normal 5V
Reference voltage of A/D Converter, normal 3.3V and 5V
※1 D1M1, D1Lx have no ISOVDD, but internal voltage from REG1VCC is also supplied to ISO digital circuit.
Table 3-2: Current measurement jumpres for I/O port supply
Port buffers P0 and JP0; nominal 3.3 V and 5 V
Port buffers port group P1,and P2; nominal 3.3 V and 5 V
Port buffers port group P3; nominal 3.3 V and 5 V
Port buffers ports P43_0 to P43_6, port groups 46, 47; nominal 3.3 V and 5 V
Port buffers ports P43_7 to P43_12; nominal 3.3 V and 5 V
Port buffers port group P42; nominal 3.3 V and 5 V
Port buffers port groups P44, P45 (VO0 RSDS); nominal 3.3 V and 5V.
Port buffers port group P40 (VI0 MIPI I/F); nominal 3.3 V
Port buffers port group P21 (serial flash and MLB); nominal 3.3 V and 5V.
Port buffers port groups P16 and P17 (Stepper Motor Controller/Driver) ;
• nominal 5 V when used for stepper motor operation
• nominal 3.3 V and 5 V when not used for stepper motor operation
Ports buffers port groups P10 and P11 (A/D Converter analog circuits and input
buffers); nominal 3.3 V and 5 V
DDR2-SDRAM I/F (except SDRBCK, SDRBCKB) ; nominal 1.8 V
Notes on current measurement:
Currently, the reset line is not pulled-up to full EVCC voltage. This is caused by the drop out voltage of LED24
“RESET ACT” (V
RESET
is only ~3.7V when EVCC is 5V). This leads to an EVCC leakage current caused by the
RESETZ input buffer. To correctly measure the EVCC current, please add a 6.2kΩ resistor in parallel to LED24
“RESET ACT” on the Mango Main Board.
