San Jose, Calif. Renesas Technology America expanded their M16C family of 16-bit microcontrollers, adding 12 M16C/64 group models and 20 M16C/65 group models for car audio, home audio, and similar consumer products, as well as industrial applications. The devices offer the flexibility customers need to implement system functional enhancements and version upgrades of embedded system designs. The microcontrollers are fully compatible with the previous-generation products, maximizing the value of customers' engineering investments.
The microcontrollers in M16C/64 and M16C/65 groups operate at 2.7 V to 5.5 V and have a high-performance M16C/60 16-bit CPU core, which enables the use of existing code. Devices in the M16C/65 group operate at speeds up to 35 MHz, while those in the M16C/64 group run at 25 MHz. All of the devices inherit the M16C family's technical capabilities including electro-magnetic compatibility (EMI/EMS), a low-voltage detection (LVD) circuit, a watchdog timer with an independent oscillator (125 kHz) and a critical-register protection feature for enhanced fail-safe condition.
Devices in both product groups offer many improvements in the on-chip peripheral functions, which include timers, an A/D converter, serial I/O and DMA controller. The devices' 10-bit A/D converter achieves a conversion speed of 1.72 µs and offers more channels (26). The microcontrollers in the M16C/65 group are bolstered by a power-on reset (POR) function, real-time clock (RTC) and high-precision (32 MHz ±1.0% or less) on-chip oscillator.
On-chip flash memory is available in capacities of 128, 256 and 512 Kbytes for microcontrollers in both groups. A higher-density-capacity model (768 Kbytes) is included in the M16C/65 group. The devices also provide an extra flash memory for data storage: a bank of 8 KB data flash with an endurance of 10,000 cycles in both read and write operations.
Packages are a 100-pin LQFP (14 x 14-mm) and a 100-pin QFP (14 x 20-mm). A 128-pin LQFP (14 x 20-mm) is also available in the M16C/65 group. General-purpose versions have a -20°C to 85°C operating temperature range; wide-temperature-range devices operate from -40° to 85°C.
