This comprehensive guide covers the 10M16SAU169I7G datasheet highlights, pinout, key electrical parameters, and practical design considerations.
1. 10M16SAU169I7G Overview & Part Number Decoding
The 10M16SAU169I7G belongs to the Intel (Altera) MAX 10 FPGA family — a single-chip, non-volatile FPGA platform that eliminates the need for external configuration flash. The part number decodes as follows:
- 10M16 – MAX 10 device with 16,000 logic elements
- S – Single power-supply (integrated 1.2 V core regulator)
- A – Analog block enabled (dual 12-bit ADC)
- U169 – 169-ball UBGA package (11 mm × 11 mm)
- I – Industrial temperature range (−40 °C to +100 °C)
- 7 – Speed grade 7 (highest performance tier)
- G – Lead-free (RoHS compliant)
Unlike SRAM-based FPGAs that require external configuration flash or EEPROM, the MAX 10 stores its bitstream in on-chip flash memory, enabling instant-on operation within milliseconds of power-up. This makes the 10M16SAU169I7G especially attractive for safety-critical and latency-sensitive applications.

6. FAQ – 10M16SAU169I7G
What is the difference between the 10M16SAU169I7G and 10M16SAU169C8G?
The main differences are temperature range and speed grade. The I7G variant supports the industrial temperature range (−40 °C to +100 °C) with speed grade 7 (fastest), while the C8G variant is rated for commercial temperature (0 °C to +85 °C) with speed grade 8 (slower). The I7G is preferred for harsh-environment and industrial applications.
Does the 10M16SAU169I7G require external configuration memory?
No. The MAX 10 family features internal flash configuration memory, eliminating the need for external SPI flash or EEPROM. The device stores its bitstream on-chip and boots instantly within milliseconds of power-up. It also supports dual-image boot for safe remote firmware updates.
What development tools are needed to program the 10M16SAU169I7G?
You need the Quartus Prime Lite Edition (free download from Intel/Altera), which includes synthesis, place-and-route, timing analysis, and the JTAG programmer. A USB-Blaster or USB-Blaster II cable is used for JTAG programming. For simulation, ModelSim-Intel Starter Edition is included at no cost.
How many ADC channels does the 10M16SAU169I7G have?
The 10M16SAU169I7G integrates a dual 12-bit ADC capable of sampling at up to 1 MSPS. It supports up to 18 single-ended analog input channels, plus an internal temperature sensor and on-chip voltage reference — making it ideal for mixed-signal designs without requiring external ADC ICs.
What is the maximum operating frequency of the 10M16SAU169I7G?
The speed grade 7 designation indicates the fastest performance tier in the MAX 10 family. The four integrated PLLs support clock management up to 500 MHz. Actual operating frequency for user logic depends on design complexity and timing closure in Quartus Prime.
Can the 10M16SAU169I7G interface with DDR3 memory?
Yes. The MAX 10 family supports DDR2, DDR3, LPDDR2, and SRAM external memory interfaces through dedicated I/O pins with DQS-based capture. However, the U169 package has a limited pin count (130 I/O), so designers should verify sufficient pins are available for the desired memory bus width plus other peripherals.
