10M16SAU169I7G Datasheet, Specifications & Application Guide – Altera MAX 10 FPGA

The 10M16SAU169I7G is a high-performance, non-volatile FPGA from the Intel (Altera) MAX 10 family. Built on 55nm flash process technology, this device integrates 16,000 logic elements, an analog-to-digital converter (ADC), and user flash memory into a compact UBGA-169 package. It is designed for industrial-grade applications operating from -40°C to +100°C, making it ideal for embedded control, motor drive, sensor interfaces, and IoT edge processing. This comprehensive guide covers the 10M16SAU169I7G datasheet specifications, pinout, block diagram, application circuits, and design tips.

Key Specifications & Parameters

The table below summarizes the critical electrical and functional parameters of the 10M16SAU169I7G. These values are extracted from the official Altera MAX 10 datasheet and distributor specifications.

The MAX 10 family's single-chip, non-volatile architecture eliminates the need for external configuration memory, reducing board space and BOM cost. The integrated ADC is especially valuable for mixed-signal applications like sensor interface designs.

Block Diagram & Architecture

The following block diagram illustrates the internal architecture of the MAX 10 10M16 FPGA, showing the relationship between logic elements, embedded memory blocks, PLLs, the ADC module, and the I/O ring:

Key architectural highlights include:

• Instant-On Configuration: Internal flash stores the FPGA bitstream, enabling the device to configure itself at power-up without external flash memory.
• Dual Configuration Images: Supports two bitstream images for remote update with automatic fallback, critical for industrial FPGA deployments.
• Integrated 12-bit ADC: A successive-approximation ADC with up to 18 analog input channels, eliminating external ADC ICs in many designs.
• M9K Memory Blocks: Each block provides 9,216 bits of configurable RAM, supporting single-port, dual-port, ROM, and FIFO modes.

Pinout & Package Information

The 10M16SAU169I7G is housed in a UBGA-169 (Ultra-Thin Fine-Pitch BGA) package measuring 11 mm × 11 mm with 0.8 mm ball pitch. This compact form factor makes it suitable for space-constrained industrial and IoT applications.

The U169 package provides 130 user I/O pins organized across multiple I/O banks. Each bank can be independently configured with different I/O voltage standards. The pinout supports:

• 8 I/O Banks: Independently powered, supporting voltage levels from 1.0 V to 3.3 V per bank.
• LVDS Support: Up to 22 differential pairs for high-speed serial interfaces.
• DDR3 Memory Interface: Dedicated pins with DQS strobe support for external DDR3 SDRAM at up to 300 MHz.
• JTAG Interface: Standard 4-pin JTAG (TCK, TDI, TDO, TMS) for programming and debugging.
• ADC Input Pins: Dedicated analog input pins connected to the internal 12-bit ADC.

Typical Application Circuit

The MAX 10 FPGA Development Kit showcases a complete reference design around the 10M16 device. The image below shows the development board with peripheral interfaces that demonstrate typical application circuits:

Common application circuits for the 10M16SAU169I7G include:

• Power Supply: 1.2 V core (VCC), 2.5 V PLL (VCCA), and 3.3 V I/O (VCCIO) rails with proper decoupling capacitors (100 nF ceramic per power pin, 10 µF bulk).
• Configuration: No external flash required — the device configures from internal flash. An optional JTAG header connects to the Intel USB Blaster II for programming.
• Clock Source: A 50 MHz oscillator feeds the PLL inputs, which generate internal clocks up to 450 MHz.
• DDR3 Interface: A 16-bit wide DDR3 SDRAM interface for high-bandwidth data buffering in embedded memory applications.
• Mixed-Signal: The integrated ADC samples analog signals through dedicated input pins, useful for temperature monitoring, voltage sensing, and basic data acquisition.

Design Guide & Development Tools

Developing with the 10M16SAU169I7G requires the Quartus Prime Lite Edition (free), which provides full support for the MAX 10 family including synthesis, place-and-route, timing analysis, and programming.

Development Workflow

1. Install Quartus Prime Lite: Download from the Intel FPGA website. The Lite edition fully supports MAX 10 at no cost.
2. Create a Project: Select the 10M16SAU169I7G as your target device. Assign pin locations using the Pin Planner.
3. Write HDL: Use Verilog or VHDL. The MAX 10 supports SystemVerilog constructs in Quartus Prime.
4. Simulate: Use ModelSim-Intel Edition (included) for RTL and gate-level simulation.
5. Compile & Program: Generate a .pof file for internal flash programming via USB Blaster II or .sof for JTAG SRAM download.
6. ADC Configuration: Use the Altera Modular ADC IP core in Platform Designer (Qsys) to set up sampling rate, channels, and sequencing.

Design Tips

• Use the dual-boot feature for fail-safe remote firmware updates — store factory and application images in separate flash sectors.
• The internal oscillator can clock the ADC without an external crystal for basic analog monitoring applications.
• Leverage Nios II soft processor IP for embedded processing tasks — the 10M16 has ample logic for a Nios II/e plus peripherals.
