Product details
Overview
MAXQ610B-0000+ from Maxim Integrated is a 16-bit RISC microcontroller optimized for ultra-low-power infrared remote control systems, featuring 64KB flash, 2KB SRAM, integrated IR carrier generation and modulation, and 32 general-purpose I/O pins in a 40-pin TQFN-EP package. It operates from 1.70V to 3.6V and delivers 12 MIPS at 12MHz with single-cycle instruction execution.
For engineers reviewing the MAXQ610B-0000+ datasheet, MAXQ610B-0000+ pinout, MAXQ610B-0000+ application, or MAXQ610B-0000+ equivalent, this device is selected for battery-powered universal remotes requiring secure firmware partitioning, sub-µA stop-mode current (0.2µA typ), and hardware-accelerated IR transmission with 25mA sink capability on IRTX.
Technical Context
The MAXQ610B-0000+ implements a single-cycle 16-bit MAXQ RISC core with three independent data pointers, dedicated code-space read pointer, and 16×16-bit general-purpose registers. Its IR subsystem includes programmable carrier frequency generation (fIR = fCK/2), burst-count mode, and independent external modulator output (IRTXM).
Power management integrates a nanopower 8kHz ring oscillator wake-up timer, power-fail warning/reset detection (VPFW = 1.8V, VRST = 1.67V), and stop mode with configurable power-fail monitor enabling. Memory protection uses a secure MMU supporting multiple privilege levels to isolate applications and prevent IP extraction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit MAXQ RISC with single-cycle execution (83.3ns @12MHz); enables 12 MIPS active performance at minimal power. |
| Memory | 64KB flash (512-byte sectors, 20k erase/write cycles) + 2KB SRAM; supports in-application programming and secure IP partitioning. |
| IR Capability | Hardware carrier generation (fIR = fCK/2), flexible modulation, and 25mA-sink IRTX output; eliminates external driver ICs in remote designs. |
| Low-Power Modes | Stop mode draws 0.2µA (typ) at +25°C with power-fail monitor disabled; resumes in 375µs + 8192×tHFXIN. |
| I/O & Peripherals | 32 GPIOs (MAXQ610B), two USARTs, SPI master/slave, two 16-bit timers/counters, power-fail detection, and JTAG debug interface. |
| Supply Range | 1.70V to 3.6V operation; includes internal 1.8V regulator (VREG18 = 1.8V ±0.18V) and brownout reset (VRST = 1.67V). |
Pinout & Package
MAXQ610B-0000+ is housed in a 40-pin TQFN-EP (exposed pad) package, 6mm × 6mm × 0.8mm, with GND connected internally to the exposed pad. The package provides 32 GPIOs, dedicated IR transmit/receive pins (IRTX/IRRX), dual USART, SPI, JTAG, and power-fail/reset circuitry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (pins 18, 38) | Primary supply input | Accepts 1.70V–3.6V; powers core, peripherals, and I/O; requires local 1µF ceramic decoupling. |
| GND (exposed pad) | Ground reference | Internally connected to die ground; must be soldered to PCB ground plane for thermal and EMI performance. |
| IRTX (pin 39) | IR transmit output | Open-drain capable of sinking 25mA; drives IR LED directly; defaults to high-Z after reset. |
| IRRX (pin 40) | IR receive input | Schmitt-triggered input with 50ns pulse-width rejection; interfaces to IR photodiode preamp outputs. |
| HFXIN/HFXOUT (pins 21/22) | High-frequency clock source | Supports 1–12MHz crystal/resonator or external clock; determines system clock (fCK) and IR carrier frequency. |
| P0.0 (pin 1) | Alternate function: IRTXM | Independent IR modulator output; used with external carrier generator for custom modulation schemes. |
| RESET (pin 37) | Active-low reset I/O | Open-drain input/output with internal pullup; asserts reset when driven low; driven low by internal POR/BOR. |
Key Features
| Feature | Design Value |
|---|---|
| Secure MMU | Enables multi-application privilege levels (Table 1), preventing unauthorized access to code/data and protecting customer firmware IP. |
| IR Hardware Acceleration | Dedicated carrier generation and modulation logic offloads CPU; supports burst-count mode for NEC/RC-5 protocols without software timing loops. |
| Nanopower Wake-Up Timer | 8kHz ring oscillator (1.7–2.4kHz at VDD = POR voltage) enables precise, ultra-low-power periodic wake-up for polling or sensing. |
| Power-Fail Detection | Monitors VDD with separate VPFW (1.8V) and VRST (1.67V) thresholds; generates interrupt before reset to allow safe flash write abort or state save. |
| Flexible I/O Configuration | All GPIOs default to high-Z after reset; software-configurable as digital I/O, UART/SPI pins, or edge-triggered interrupts (INT0–INT15). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAXQ610A-0000+ | 32-pin TQFN package with 24 GPIOs; identical core, memory, and peripheral specs except reduced I/O count and smaller footprint. | Suitable for space-constrained remotes where 24 I/Os suffice; lacks P3.x interrupt pins and some SPI/JTAG pins present on MAXQ610B. | Select MAXQ610A-0000+ when board area is critical and full 32 I/Os are unnecessary; verify pin compatibility for existing layout reuse. |
| MAXQ610J-0000+ | 44-pin TQFN package with 32 GPIOs plus additional JTAG and analog-capable pins; same core/peripherals but larger package and enhanced debug accessibility. | Preferred for development and production test environments requiring full JTAG visibility and margin for future analog sensor expansion. | Choose MAXQ610J-0000+ for prototyping or high-reliability industrial controls needing extra debug signals and layout flexibility. |

FAQ
What is the maximum system clock frequency supported by the MAXQ610B-0000+?
The MAXQ610B-0000+ supports DC to 12MHz system clock operation across its full 1.70V–3.6V supply range. At 12MHz, it achieves nearly 12 MIPS with most instructions executing in a single cycle (83.3ns). The clock may be sourced from an external crystal/resonator (HFXIN/HFXOUT) or external clock signal applied to HFXIN.
How many general-purpose I/O pins does the MAXQ610B-0000+ provide?
The MAXQ610B-0000+ provides 32 general-purpose I/O pins, distributed across Ports P0–P3. This matches the 40-pin TQFN package variant explicitly designated in the ordering table. All I/Os default to high-impedance after reset and require software configuration for direction and function.
Does the MAXQ610B-0000+ include hardware support for infrared transmission?
Yes, the MAXQ610B-0000+ integrates dedicated IR hardware including carrier frequency generation (fIR = fCK/2), modulation control, burst-count mode, and a high-current IRTX output capable of sinking 25mA. It also provides IRTXM for external carrier modulation, enabling full protocol compliance without external timing ICs.
What is the typical current consumption of the MAXQ610B-0000+ in stop mode?
The MAXQ610B-0000+ consumes 0.2µA (typical) in stop mode at +25°C with the power-fail monitor disabled. Maximum stop-mode current is 2.0µA across the 0°C to +70°C temperature range. Wake-up sources include external interrupts, timer interrupts, and the power-fail interrupt.
Is the MAXQ610B-0000+ RoHS-compliant and lead-free?
Yes, the MAXQ610B-0000+ is RoHS-compliant and lead-free, as indicated by the '+' suffix in the part number. It uses a lead(Pb)-free finish on its 40-pin TQFN-EP package and meets JEDEC J-STD-020 moisture sensitivity level 3 requirements.
