4. Pinout, Package & Footprint (U169 UBGA)
The 10M16SAU169I7G is housed in a 169-ball UBGA package with a compact 11 × 11 mm body and 0.8 mm ball pitch. The package provides 130 user I/O pins across 8 I/O banks, supporting a wide range of voltage levels and differential signaling standards.
Pin Categories
- User I/O: 130 general-purpose I/O pins configurable per bank voltage
- Dedicated Clock Inputs: 4 dedicated clock input pins for low-jitter clock distribution
- JTAG: TDI, TDO, TMS, TCK for programming and debug via IEEE 1149.1
- ADC Inputs: Dedicated analog input pins routed to the dual 12-bit ADC
- Power/Ground: VCC (1.2 V core), VCCIO (per-bank I/O), VCCA (analog PLL), GND
PCB Design Tips: Use a minimum 4-layer stackup. Place 100 nF decoupling capacitors close to each VCC/VCCIO ball. Route LVDS pairs with controlled impedance (100 Ω differential). Keep analog input traces short and shielded from digital switching noise.
5. Application Circuit & Design Guidelines
The 10M16SAU169I7G is a versatile FPGA suited for a variety of embedded and industrial applications. The integrated ADC and instant-on capability make it particularly attractive for mixed-signal designs that require fast startup and analog sensing.
Typical Application Areas
