Product details
Overview
SLG46827-AG from Renesas Electronics is an AEC-Q100 qualified programmable mixed-signal matrix IC with in-system debug, dual rail-to-rail analog comparators (ACMPxH/ACMPxL), two voltage references, 25 MHz oscillator, and 11 combination function macrocells. It operates across 2.5–5 V (VDD) and 1.8–5 V (VDD2 ≤ VDD) supply rails and supports automotive infotainment and ADAS subsystems requiring configurable logic and analog sensing.
For engineers reviewing the SLG46827-AG datasheet, SLG46827-AG pinout, SLG46827-AG application, or SLG46827-AG equivalent, this device delivers field-programmable analog-digital signal conditioning, timing generation, and state-machine control in a single 20-pin TSSOP package-ideal for space-constrained automotive modules needing functional safety alignment and low-power mixed-signal integration.
Technical Context
The SLG46827-AG implements a reconfigurable connection matrix linking 11 combination function macrocells (including selectable 2-/3-/4-bit LUTs, DFF/LATCH, pattern generators, and ripple counters) and eight multi-function macrocells (with integrated 8-/16-bit delay/counters). Its analog subsystem includes four independent comparators-two high-speed (ACMPxH) and two low-power (ACMPxL)-each with programmable hysteresis and input buffering.
Dual-supply operation enables independent interfacing with 1.8 V logic and 3.3/5 V analog domains. The device integrates three oscillators (2.048 kHz, 2.048 MHz, 25 MHz), an analog temperature sensor (±2.5 °C accuracy), I²C serial interface (address 0x20–0x2F), and Power-On Reset with configurable delay-supporting deterministic startup in automotive ECUs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SLG46826-AG | Same architecture but lacks analog temperature sensor and one ACMPxH; 10 macrocells instead of 11 | Not suitable for thermal monitoring or dual high-speed event detection paths | Select SLG46826-AG only if temperature sensing and full comparator complement are unnecessary |
| SLG46537V-DIE | Die form factor; no TSSOP packaging; identical macrocell count and oscillator set but no I²C debug interface | Requires custom substrate and wire bonding; not drop-in replaceable for board-level designs | Choose SLG46537V-DIE only for embedded module integration where debug access is handled externally |
Compared with SLG46826-AG and SLG46537V-DIE, the SLG46827-AG uniquely combines AEC-Q100 qualification, in-system debug, analog temperature sensing, and full 4-comparator capability in a standard 20-pin TSSOP-making it the only option for production automotive modules requiring field-upgradable mixed-signal functionality with thermal awareness.

FAQ
What is the maximum operating frequency of the 25 MHz oscillator in SLG46827-AG?
The SLG46827-AG's primary high-frequency oscillator is specified at 25 MHz ±2 % over temperature (−40 °C to +105 °C) and supply (2.5–5 V). This oscillator feeds macrocell timing, counters, and I²C clock generation. It is factory-trimmed and does not require external components. The SLG46827-AG datasheet confirms stable operation up to 25 MHz under all qualified conditions-no derating required for automotive use cases.
Does SLG46827-AG support I²C multi-master configurations?
No, SLG46827-AG implements I²C slave-only functionality with fixed 7-bit addresses (0x20–0x2F). It does not support arbitration, clock stretching beyond internal delays, or master-initiated transactions. The SLG46827-AG relies on an external controller (e.g., MCU) to manage bus arbitration and command sequencing-consistent with its role as a peripheral configurator, not a system host.
Can SLG46827-AG generate PWM signals without external components?
Yes, SLG46827-AG can generate precise PWM waveforms using its programmable pattern generator macrocell or LUT+counter combinations. Duty cycle and frequency are fully configurable via NVM settings and can be updated dynamically over I²C. The SLG46827-AG supports resolutions up to 16 bits (via 16-bit delay/counter) and frequencies up to 25 MHz-enabling direct LED dimming, motor control enable signals, or audio tone generation without external timers or DACs.
Is the analog temperature sensor in SLG46827-AG calibrated at production?
Yes, the analog temperature sensor in SLG46827-AG undergoes single-point factory calibration at 25 °C, with linearization coefficients stored in NVM. The SLG46827-AG delivers ±2.5 °C accuracy across −40 °C to +105 °C without user calibration. Output is ratiometric to VDD and readable via comparator threshold comparison or external ADC-no additional compensation circuitry is needed for basic thermal trip detection.
How many times can the NVM in SLG46827-AG be reprogrammed?
The non-volatile memory in SLG46827-AG supports ≥100 write/erase cycles under recommended operating conditions (VDD = 3.3 V ±10 %, TA = 25 °C). Endurance is verified per JEDEC JESD22-A117. Each programming cycle requires full sector erase; partial writes are not supported. The SLG46827-AG datasheet specifies that NVM retention exceeds 10 years at +105 °C ambient-ensuring reliability across automotive service life.
