Austin, TX--May 22, 1997--Motorola's (Austin, TX) Microcontroller Technologies Group announced the expansion of its line of microcontrollers with integrated Flash Electrically Erasable Programmable Read Only Memory (EEPROM).
The 68HC916R1, a member of the high-performance 16-bit 68HC16 microcontroller family, is targeted for applications such as automotive engine and transmission control, smart meters, industrial controllers, and other products that benefit from the unique capabilities that on-chip Flash memory offers.
The new 68HC916R1 offers 48 kbytes of Flash EEPROM and 2 kbytes of block-erasable Flash EEPROM. Integrated Flash memory allows end-of-line programming and more importantly, in-circuit reprogramming to allow periodic upgrades and maintenance in the field. In addition, it allows for reduced system costs due to fewer external components; reduced board space and complexity; increased system reliability; improved memory access times up to 50 percent (compared to off-chip Flash memory); and therefore overall system performance increases.
The new 68HC916R1 is based on Motorola's modular design methodology, which facilitates the rapid development of new derivatives tailored for specific applications or customers. Motorola's 16-bit 68HC16 family, as well as its 32-bit 68300 family and new 68HC12 family, make use of an extensive library of peripheral modules that interface through similar bus interfaces.
The new chip also includes Motorola's unique Background Debug Mode (BDM) in-circuit debugging feature that simplifies code development and debug. Background Debug Mode allows read and write access of the microcontroller's registers and memory, and offers a comprehensive set of debug commands. This allows field re-programming to be done on-board or even from a remote site, eliminating the need to remove the MCU or the electronic module.
Development support for these 68HC16 family members includes both Motorola and third-party tools. Motorola offers its Modular Evaluation Board (MEVB1632), its MMDS1632 Modular Development System, SDI serial interface, and the RTEK embedded kernel.
A convenient platform to create, develop and debug application code, the MEVB1632 is a two-board system consisting of a modular platform board and an MCU personality board, which is specific to the microcontroller device being evaluated.
The MMDS1632 provides complete hardware and software, real-time, in-circuit emulation for embedded applications based on 68HC16 microcontrollers. The full-featured, modular MMDS1632 system consists of a station module, device-specific microcontroller personality board, package-specific personality and target boards as well as emulation software, HIWARE HI-LITE debugging software, and the necessary interfaces.
The SDI interface is a serial in-circuit debugger that makes use of the Background Debug Mode on 68HC16 devices. It allows quick verification and updating of customer's embedded software.
A full-featured real-time operating system, the RTEK kernel supports the 68HC16 as well as five other Motorola microcontroller families.
The 68HC16 family is also supported with both hardware and software tools by a number of independent suppliers.
The 68HC916R1 is available in a 132-pin Plastic Quad Flat Pack (PQFP) package, priced at U.S.$27.40 per unit in 10,000-piece quantities (suggested list). Motorola also offers a ROM version, the 68HC16R1, which is available now in a 132-pin PQFP package, priced at U.S.$16.92 per unit in 10,000-piece quantities (suggested list).
