M68LC302CPU16VCT

The M68LC302CPU16VCT is a low-cost integrated multiprotocol microprocessor from NXP Semiconductors based on a static M68000 core. Running at 166 MHz with 3.3 V I/O and a compact 100‑LQFP (14 × 14 mm) package, it targets embedded and industrial designs that require a highly integrated processor with on‑chip communications and system peripherals.

Designed for embedded communications, low‑power and height‑restricted applications, the device combines a 68000 core, on‑chip DMA, timers, dual‑port RAM and serial communications support to simplify board design and accelerate time to market.

Key Features

• Core  Static M68000 core supporting 8‑ or 16‑bit system operation with a clock rate of 166 MHz.
• Memory  On‑chip 1152‑byte dual‑port RAM with programmable address mapping plus support for DRAM via an on‑chip DRAM refresh controller.
• Bus, DMA and Interrupts  Independent DMA (IDMA) controller, system bus with general‑purpose DMA channel and an interrupt controller with two modes of operation.
• Communications Processors  On‑chip main controller (RISC CPM) and two full‑duplex serial communications controllers (SCCs) supporting HDLC/SDLC, UART and BISYNC protocols.
• Timers and Watchdog  Three timers including a watchdog timer and a periodic interrupt timer (PIT) for reliable timing and supervisory functions.
• Memory Interface & Boot  Glueless interface to EPROM, SRAM, Flash EPROM and EEPROM with four programmable chip‑select lines and a wait‑state generator; allows boot in 8‑bit mode with switch to 16‑bit operation.
• Clock & Low‑Power Modes  On‑chip clock generator and PLL supporting 32 kHz or 4 MHz crystals, plus new low‑power standby modes with wake‑up from two pins or PIT.
• Package & Temperature  100‑LQFP (14 × 14 mm) surface‑mount package; industrial operating temperature range of −40 °C to 85 °C.
• System Control  Programmable chip selects, system status/control logic, freeze control for debugging and hardware watchdog capabilities.
• Compliance  RoHS compliant.

Typical Applications

• Embedded Communications Modules  Use the integrated RISC communications processor and dual SCCs for protocol handling and serial interfacing in networked devices.
• Portable and Low‑Power Devices  Low‑power standby modes, on‑chip clock/PLL and a compact LQFP package make the device suitable for portable electronics and height‑restricted form factors.
• Industrial Control and Automation  Industrial qualification and a wide operating temperature range support control, monitoring and I/O tasks in industrial systems.
• Compact System Controllers  On‑chip DMA, timers, watchdog and dual‑port RAM enable compact, integrated controllers for embedded single‑board systems.
• PCMCIA or Height‑Restricted Designs  Low profile 100‑LQFP package suits applications with strict space and height constraints.

Unique Advantages

• Highly integrated architecture: Combines M68000 core, DMA, timers, dual‑port RAM and communications processors on a single chip to reduce BOM and simplify board layout.
• Flexible memory interfacing: Glueless connections to EPROM/SRAM/Flash/EEPROM and programmable chip‑selects streamline external memory designs and boot options.
• Built‑in communications support: Two full‑duplex SCCs and a CPM RISC controller support multiple serial protocols without heavy external logic.
• Robust timing and supervision: Multiple timers including PIT and watchdog provide reliable system supervision and deterministic interrupt timing.
• Low‑power and space‑efficient: On‑chip PLL, low‑power standby modes and a compact 100‑LQFP footprint enable power‑sensitive and size‑constrained applications.
• Industrial readiness: Rated for −40 °C to 85 °C and provided in an industry‑standard surface‑mount package suitable for rugged embedded deployments.
