Led by the industry’s first programmable 14-bit successive-approximation-register analog-to-digital converter (SAR ADC), four new AnalogPAK ICs unveiled by Renesas Electronics also include lower-power and automotive-qualified devices.
These can be thought of as baby-FPGAs that feature a small number of lookup tables (LUTs) and a math block to enable programmable digital functions. However, they also feature analog programmable components such as comparators, op amps, ADC and digital-to-analog converter (DAC), filters, a temperature sensor, etc. All four products, along with evaluation/programming boards, are currently available from distributors.
Renesas will demonstrate these new AnalogPAK devices at the electronica Trade Fair from November 12-15, 2024 in Munich – Hall B4, Stand #179.
AnalogPAK SLG47011: Low-Power Device with 14-bit SAR ADC
The SLG47011 AnalogPAK device delivers a new level of performance for configurable analog integrated circuits. It includes a rich set of digital and analog features, including a programmable, multichannel 14-bit SAR ADC with programmable gain amplifier (PGA). The SLG47011 also has flexible, user-defined, power-saving modes for all macrocells, enabling designers to switch off some blocks in sleep mode and therefore reduce power consumption to the microamp level.
The SLG47011 can extend the performance of, or be utilized to offload, an MCU. It may also be used with an MCU to replace a complex analog front-end (AFE). Key functions supported by the SLG47011 include measurement, data processing, logic control, and data output.
Among the key parameters of SLG47011 are:
- Vdd = 1.71 to 3.6 V
- SAR ADC: Up to 14-bit, up to 2.35 Msamples/s in 8-bit mode
- PGA: Six amplifier configurations, rail-to-rail input/output, 1X to 64X gain
- DAC: 12 bit, 333 ksamples/s
- Hardware math block for multiplication, addition, subtraction, and division operations
- Flexible 4096-word memory table block
- Oscillators: 2/10 kHz and 20/40 MHz
- Analog temperature sensor
- Highest number of highly configurable counter/delay blocks
- I2C and SPI communication interfaces
- Tiny 16-pin QFN 2.0- × 2.0- × 0.55-mm, 0.4-mm-pitch package

SLG47001/3 AnalogPAK Devices
The SLG47001 and SLG47003 enable the implementation of precise measurement systems with a low price point and a very compact package. Among their many applications are gas sensors, power meters, measurement equipment, servers, wearables, industrial robots, and industrial and smart-home sensor modules.
Features include:
- Two ultra-low-offset op amps: 9 µV (max.)
- Two 10-bit digital rheostats
- Six-channel sampling comparator
- Analog switch
- Voltage reference
- 59-byte pattern generator
- 2k/10k/25-MHz oscillators
- Fully configurable blocks: LUTs, flip-flops, shift registers, timers, counters, delays
- Available packages: 20-pin STQFN—2.0 × 3.0 × 0.55 mm, 0.4-mm pitch (SLG47001); 24-pin STQFN—3.0 × 3.0 × 0.55 mm, 0.4-mm pitch (SLG47003)
The datasheet can be found here.
SLG47004-A AnalogPAK Device
The SLG47004-A delivers the functionality of the SLG47004 devices with the addition of automotive qualification Grade 1 for applications such as infotainment, navigation, chassis and body electronics, automotive display clusters, and more. The new devices support a temperature range of –40 to 125°C.
The datasheet can be found here.
Product Overview Presentation
Editor’s note: I had Renesas brief me on the product line last week with a presentation during our recorded Zoom call, which gave me the opportunity to ask them some unprepared questions. Here’s the video recording of that Zoom call. If you’re unfamiliar with Renesas’ very-low-cost baby-FPGAs that have op amps, comparators, an ADC, and other analog blocks in addition to various LUTs, I think it’s a good overview of what’s in the chips. It also shows how their configuration tool is used.
