• LTE power saving mode (PSM) floor current: 2.7 μA @ 3.7 V
• eDRX current: 19 μA (Cat-M1), 33 μA (Cat-NB1) @ 3.7 V (UICC included)

Absolute Maximum Ratings:

Key Specs:

• Microcontroller: Arm Cortex-M33
• Flash memory: 1 MB
• RAM: 256 kB
• ADC: 12-bit, 200 ksps, 8 configurable channels

• LTE output power: Up to 23 dBm
• GPIO pins: 32
• Package dimensions: 10 × 16 × 1.04 mm

Features:

• Arm TrustZone and CryptoCell 310 for security
• Integrated GPS L1 C/A and QZSS L1 C/A receiver
• Up to 4x SPI master/slave with EasyDMA
• Up to 4x I2C compatible two-wire master/slave with EasyDMA
• Up to 4x UART (CTS/RTS) with EasyDMA
• I2S and Digital microphone interface (PDM) with EasyDMA
• Power saving features: DRX, eDRX, PSM
• Single 50 Ω antenna interface

Applications:

• Sensor networks
• Logistics and asset tracking
• Smart energy
• Smart building automation
• Smart agriculture
• Industrial
• Retail and monitor devices
• Medical devices
• Wearables

Package:

• LGA (10 × 16 × 1.04 mm)

• Up to two PDM microphones configured as a left/right pair using the same data input
• 16 kHz output sample rate, 16-bit samples
• EasyDMA support for sample buffering
• HW decimation filters
• Selectable ratio of 64 or 80 between PDM_CLK and output sample rate

The PDM module illustrated below is interfacing up to two digital microphones with the PDM interface. EasyDMA is implemented to relieve the real-time requirements associated with controlling of the PDM slave from a low priority CPU execution context. It also includes all the necessary digital filter elements to produce pulse code modulation (PCM) samples. The PDM module allows continuous audio streaming.

I appreciate your detailed request, but I need to clarify an important limitation:

The image provided does not contain a pin diagram or pinout table. The image shows only the Nordic Semiconductor logo and is not a pin configuration diagram.

The text section you've provided (6.4.1 Pin configuration) describes the GPIO port peripheral and its configurable parameters, but it does not contain a pin assignment table for the NRF9161-LACA-R7.

What I need to proceed:

To extract the pinout for NRF9161-LACA-R7, I require:

1. A pin diagram image showing pin numbers (1, 2, 3, …) and their labels
2. A pin assignment table (typically titled "Pin assignments" or "Pinout") that lists:
   • Pin numbers
   • Pin names (e.g., P0.00, P0.01, VDD, GND, etc.)
   • Pin types/functions
   • Descriptions

The datasheet section you provided references "Pin assignments on page 450" — that section (or the pin diagram from the package drawing) is what I need.

Please provide:

• The pin diagram image for the NRF9161-LACA-R7 package
• The pin assignment table from page 450 or the relevant package section

Once you supply those, I can extract a clean, accurate pinout table.

Maximum ratings are the extreme limits to which the chip can be exposed for a limited amount of time without permanently damaging it. Exposure to absolute maximum ratings for prolonged periods of time may affect the reliability of the device.

No internal voltage boost converters
