KMC68LC302AF16CT

The KMC68LC302AF16CT is an integrated multiprotocol microprocessor based on a static M68000 core running at 16 MHz. It combines a single 8/16-bit core with on-chip system controllers and peripheral subsystems to address space- and power-constrained embedded applications.

Designed for embedded markets that require integrated communications, DMA and memory control, this device delivers a compact, surface-mount 100-LQFP (14×14) package, 5 V I/O and an operating temperature range of 0 °C to 70 °C for standard commercial designs.

Key Features

• Core – Static M68000 core supporting 8- or 16-bit M68000 family systems, operating at 16 MHz for predictable embedded processing.
• Memory – On-chip 1,152-byte dual-port RAM and support for DRAM via an integrated DRAM refresh controller to simplify local data sharing and memory refresh tasks.
• DMA & Interrupts – Independent DMA (IDMA) channels and a versatile interrupt controller with multiple modes to offload data movement and manage real-time events.
• Communications / Co-processor – On-chip communications processor (RISC-based main controller) with two full-duplex Serial Communication Controllers (SCCs) supporting HDLC/SDLC, UART, BISYNC and related modes.
• Timers & Watchdog – Multiple timers including a watchdog timer and a periodic interrupt timer (PIT) for deterministic timing and system supervision.
• System & Clock – On-chip clock generator and PLL with support for 32 kHz or 4 MHz crystals; programmable chip-selects (four) with wait-state generator logic and glueless interface to EPROM/SRAM/Flash/EEPROM.
• I/O & Interfaces – Parallel I/O ports (some with interrupt capability) and additional interfaces including GCI for system integration.
• Package & Power – Low-profile 100-LQFP (14×14) surface-mount package suitable for height-restricted applications and featuring new low-power standby modes described in the product brief.
• Operating Conditions – 5 V I/O and specified commercial operating temperature range of 0 °C to 70 °C.

Typical Applications

• PCMCIA and height-restricted modules – Low-profile 100-LQFP packaging makes the device suitable for compact card-edge and similar form-factor devices.
• Low-power portable equipment – On-chip low-power modes, PLL-based clocking and integrated peripherals reduce external component count for portable embedded systems.
• Embedded communications controllers – Integrated SCCs, communications processor and DMA enable implementation of multiprotocol data link and serial communications tasks.
• Systems requiring integrated memory control – On-chip dual-port RAM and DRAM refresh controller simplify designs that need local shared memory and DRAM support.

Unique Advantages

• Highly integrated solution: Combines a static M68000 core, communications processor, dual-port RAM and peripheral controllers to reduce BOM and board complexity.
• Flexible bus operation: Supports booting in 8-bit mode with running switch to 16-bit mode and offers a glueless interface to common non-volatile and SRAM memory types.
• Space-efficient packaging: Low-profile 100-LQFP (14×14) enables use in height-restricted and compact embedded systems such as PCMCIA cards.
• On-board timing and supervision: Multiple timers including PIT and watchdog simplify deterministic scheduling and system reliability features without external timers.
• Integrated communications capability: Two full-duplex SCCs and a communications RISC controller support multiple serial protocols, reducing the need for external UART/SCC devices.
• Programmable system interfaces: Four programmable chip-select lines, wait-state logic and an on-chip PLL/clock generator make it adaptable to a variety of external memory and clock sources.
