Z8619340ASG - 8-Bit 40MHz ROMless MCU | Zilog
부품 번호: Z8619340ASG ✓ 활성Z8619340ASG 개요
A microcontroller is a programmable integrated circuit containing a processor core, memory interface, and dedicated peripherals on one chip. Within the embedded-system hierarchy, the Z8619340ASG is an 8-bit MCU, a member of the Z8 family, and a ROMless member of the Z86193 series. ROMless devices generally require program memory to be connected externally, giving the designer flexibility in firmware storage while requiring careful bus and board-level design.
The headline configuration is an 8-bit processor operating at 40 MHz in an LQFP-64 package. Because program storage is external, application code must be supplied by an external memory device rather than an internal mask-programmed or one-time-programmable ROM. This makes the device suitable for applications in which firmware is loaded, revised, or stored externally, provided that the system designer implements the required memory interface and associated circuitry.
The product listings also identify multiplication, division, and serial-interface functions. Multiplication and division support is important in embedded calculations involving scaling, timing, signal processing, and display formatting. Integrated serial capability reduces the need for separate peripheral ICs when the surrounding system can use the interfaces supported by the Z86193 family. Exact peripheral assignments, interrupt behavior, voltage limits, memory-interface details, and clock configuration must be confirmed against the manufacturer’s pin description and device documentation before layout release.
The LQFP-64 package is a surface-mount gull-wing package intended for automated board assembly and compact multilayer PCB construction. Its exposed lead geometry supports inspectable solder joints, but correct pad design, solder mask definition, and paste volume remain important. Because this is a 64-pin device, careful pin planning is necessary to avoid routing conflicts among address, data, control, serial, and general-purpose I/O signals.
Typical uses for this microcontroller family include industrial control modules, instrumentation, communication equipment, motor-control interfaces, and embedded controllers with external program memory. A design using the Z8619340ASG should be selected when its documented I/O count, external-memory architecture, 40 MHz operating speed, and family peripheral set match the product requirements. It is less suitable where a smaller package, integrated nonvolatile memory, low-power operation, or a different instruction set is required.
This page consolidates the verified package and core-device characteristics, practical PCB considerations, sourcing information, and a strict assessment of replacement candidates. It also distinguishes documented facts from parameters that must be checked in the official device documentation, helping engineers plan the MCU, memory interface, and PCB before committing the design to production.

일반적인 애플리케이션
Z8619340ASG 적합 용도: 6 애플리케이션s: Industrial Control Modules, Instrumentation and Data Acquisition, Communication Equipment, Motor and Equipment Control, External-Firmware Embedded Products, Custom HMI and Peripheral Controller.
Industrial Control Modules
The Z8619340ASG fits industrial controller designs that need an 8-bit embedded processor, external program memory, and a relatively high pin count. Its verified 40 MHz Z8 operating rating supports responsive sequencing and peripheral control, while the 64-pin LQFP provides more external connections than a small microcontroller package. Because the MCU is ROMless, the controller can use a separate memory device when code updates, configuration variants, or production-programming strategies require external storage. Firmware should validate bus timing and all port assignments against the Zilog documentation before deployment.
추천
Instrumentation and Data Acquisition
A measurement instrument can use the Z8619340ASG as the supervisory controller for sensor conditioning, range selection, calibration storage, and data handling. The 64-pin LQFP offers a practical number of connections for digital interfaces, control signals, displays, and communications, while the 8-bit Z8 core and 40 MHz rating support embedded coordination. External program memory gives designers room to select the storage density and programming method. Analog front-end accuracy, reference quality, and noise control remain separate design tasks and should not be inferred from the MCU’s clock or digital package ratings.
추천
Communication Equipment
The Z8619340ASG is suitable for protocol handling and supervisory control in embedded communications equipment that requires serial functions and a substantial I/O interface. Its documented multiplier, divider, and serial capabilities can reduce the need for discrete logic in workloads involving framing, timing, status encoding, and peripheral coordination. The 40 MHz operating rating gives designers headroom for responsive interrupt-driven routines, although actual throughput depends on instruction execution and bus timing. External program memory must be chosen and interfaced according to the Z86193 family architecture.
추천
Motor and Equipment Control
In a motor-control or equipment-control subsystem, the Z8619340ASG can execute sequencing logic, monitor discrete inputs, generate control outputs, and coordinate serial diagnostics. The 64-pin LQFP makes it appropriate for systems that need numerous digital connections and multiple peripheral functions around one controller. Its 8-bit Z8 architecture and 40 MHz rating are useful for deterministic control tasks, while multiplication and division support can assist scaling and timing calculations. Power-stage isolation, protection, grounding, and timing-margin design must be developed separately around the MCU.
추천
External-Firmware Embedded Products
The ROMless Z8619340ASG is appropriate when program storage must remain separate from the microcontroller. That architecture supports field-updatable products, shared controller platforms with configurable firmware, and production flows that benefit from using external memory devices. The 8-bit processor operates up to 40 MHz and is packaged in a 64-pin LQFP, giving a balance of processing availability and external connectivity. Designers should calculate worst-case external-bus access time and allow reset, clock, and program-verification behavior to fit the product’s update and recovery requirements.
추천
Custom HMI and Peripheral Controller
The Z8619340ASG can serve as the control processor in a custom human-machine interface or multi-peripheral controller that needs buttons, indicators, external interfaces, and sequencing logic. Its 64-pin LQFP provides more routing opportunities than a compact 8-bit package, and the 40 MHz Z8 core can support responsive event-driven operation. Serial functionality can simplify communication to a display or host, subject to the exact peripheral mapping and electrical levels of the selected board. Keep display timing, ESD protection, and connector isolation outside the MCU domain so each requirement can be verified independently.

설계 노트
Use the manufacturer’s 64-pin LQFP land pattern and verify pad dimensions, solder-mask expansion, and paste volume against the current assembly process. Route external-memory address and data signals with short, continuous paths, and place decoupling capacitors close to the supply pins identified in the device documentation. With 64 terminals, complete pin planning before routing because alternate memory functions can constrain otherwise available I/O.
Plan the external program-memory interface before fixing the PCB stack-up and layer assignments. Keep the MCU-to-memory path compact, provide continuous return paths beneath high-speed signals, and avoid routing memory buses across split power planes. If the operating clock can approach 40 MHz, evaluate setup and hold time, output impedance, load capacitance, and bus timing rather than relying only on the nominal processor frequency.
Do not treat the Z8619340ASG as containing internal program ROM; the verified device is ROMless and therefore requires an external memory solution. Also avoid assuming that a similarly rated 8-bit MCU is interchangeable. Validate pin names, voltage, clock, reset, memory interface, interrupts, serial functions, and peripheral multiplexing against the Zilog documentation before substituting another device or revising an existing board.
Confirm the exact supply-voltage range and absolute maximum limits in the Zilog device documentation before designing the power tree. Apply the manufacturer’s recommended input and output capacitance values, and account for the external memory’s supply current and signal load as separate budget items. Confirm that the chosen regulator has adequate headroom for the MCU, memory, and attached peripherals under worst-case operating conditions.
