There are four part numbers of ASR6601: ASR6601CB, ASR6601CBR, ASR6601SE, and ASR6601SER. The key feature differences between two parts numberamong the four part numbers of ASR6601 are listlisted below,. ASR6601SE and ASR6601SER can support more analog functions with more GPIOs.
Note
- Compared to the ASR6601SE (ASR6601CB), the new part number ASR6601SER (ASR6601CBR) changes only in the RSTN pin function; the RSTN pin number remains the same. All other pins are the same as those of previous part numbers.
- For the ASR6601SER (ASR6601CBR), the reset signal on the RSTN pin only resets main domain, and the Aon domain and Aonr domain keeps running. For the ASR6601SE (ASR6601CB), the reset signal on the RSTN pin will restart the whole chip, with the same function as power-on reset. As for the definition of the main domain, the Aon domain and the Aonr domain, please refer to Section 4.2: Power Supply Architecture in ASR6601 Reference Manual.
- For the software reference design, the ASR6601SER (ASR6601CBR) can only be supported by the SDK v2.0.0 or the later versions. For more details, please refer to the SDK release note.
ASR6601 has several separated power supply pins. With these separated power supply pins, the interference from digital parts of SoC to RF blocks is reduced.
ASRR6601 Power Grid is shown in the figure below:
- VDD_IN: The power supply for the PA in the RF transmitter.
- VBAT_RF: The power supply for the RF TRX, excluding the PA.
- VDCC_RF: The low power supply for RF TRX, which must be connected to VREG pin of SoC through the PCB.
- VBAT_ESD0: Power supply for digital IO.
- VBAT_ESD1: Power supply for digital IO.
- VBAT_ESD2: Power supply for digital IO.
- VBAT_ESD3: Power supply for digital IO.
- VBAT_DCC: The power supply for DCDC.
- VBAT_ESD_RTC: The power supply for IOs in RTC domain.
- VBAT_RTC: The power supply for analog blocks in RTC domain.
- VBAT_ANA: The power supply for analog blocks.
The boot mode can be configured by the levels of BOOT0 pin and the data in the Flash.
| DebugLevel | UseFlashBoot0 | FlashBoot0 | BOOT0 pin | FlashBoot1 | MainFlashEmpty | Boot Config |
|---|---|---|---|---|---|---|
| 2 | X | X | X | X | X | boot from Flash Main |
| <2 | 0 | X | 0 | X | 0 | boot from Flash Main |
| <2 | 0 | X | 0 | X | 1 | boot from Bootloader |
| <2 | 0 | X | 1 | 1 | X | boot from Bootloader |
| <2 | 0 | X | 1 | 0 | X | boot from Sys SRAM |
| <2 | 1 | 1 | X | X | 0 | boot from Flash Main |
| <2 | 1 | 1 | X | X | 1 | boot from Bootloader |
| <2 | 1 | 0 | X | 1 | X | boot from Bootloader |
| <2 | 1 | 0 | X | 0 | X | boot from Sys SRAM |
- DebugLevel, UseFlashBoot0, FlashBoot0 and FlashBoot1 is the information area of the Flash, they can be modified according to the application. MainFlashEmpty is determined by the data of address 0 in the flash Main area. If the data in the address 0 of Flash Main area is 0xFFFFFFFF, the value of MainFlashEmpty is 1, otherwise the value of MainFlashEmpty is 0. BOOT0 pin is GPIO02 in the package.
- The boot mode is selected according to the configurations when the system is in these status: first powered up, exit the Standby mode or reset.
Electrical Characteristics include absolute maximum rating, recommended operating range, TRX performance, power consumption characteristics, ESD ratings and RSTN characteristics for the SoC and module.

Note
- IDD_Standby and IDD_Stop3 are tested at 25 degrees and the RCO32K is used as the RTC clk.
- The XO32K block operates either in its normal mode or low-power mode. Through the proper design of XO32K PCB routing, the XO32K can work in its low-power mode, and in this case, the IDD current with the XO32K clk is as low as that with the RCO32K clk. For more details, please refer to ASR6601 Hardware Design Guide. Otherwise, the XO32K block shall only work in the normal mode, and the current will increase about 500nA compared with the low-power mode.
- SoC Core Supply Current refers to the power consumption of the Arm China STAR-MC1 processor and SoC TRX Supply Current refers to the power consumption of the LPWAN RF Transceiver.
For ASR6601CB/ASR6601SE RSTN, the reset signal on RSTN pin restarts the whole chip including the main domain, the Aon domain and the Aonr domain, with the function as power-on reset. With a slow rise or fall of the signal on the NRST pin when the VBAT is ready, a particular unwanted internal reset timing is generated, which will make the chip enter safe mode and erase the flash. The reference design of NRST is as below,
Note
- The parallel resistance value is recommended to be 4.7K~10K, and the parallel capacitance value is recommended to be 300pF~10nF.
- Different VDD power-on timings and unwanted reset timing must be avoided, or risks will arise. For more details, please refer to ASR6601 Hardware Design Guide.
For ASR6601CBR/ASR6601SER RSTN, the reset signal on RSTN pin only resets the main domain, which is different from the ASR6601CB/ASR6601SE RSTN. The RSTN is controlled by an external switch or one GPIO from other MCU, which can be configured to open drain output mode or push pull output mode. The reference design of RSTN pin is as below:
Note
- If MCU GPIO is configured to open drain output mode, the serial resistor may not be used, but the pull-up resistor is a must, otherwise the high RSTN will be HIZ.
- ASR6601SER (ASR6601CBR) can only be supported by the SDK v2.0.0 or the later versions. For more details, please refer to the SDK release note.
