- Sixteen 32-bit ALU registers
- Supports 8-bit, 16-bit, and 32-bit ALU operations
- 24-bit address bus
- 16-bit internal data bus
- 32-bit ALU
- C-compiler friendly instruction set
- Zero-wait state internal Flash
- 7 cycle interrupt latency (typical)
- 32x32 Multiply (signed or unsigned)
- 64/32 Divide (signed or unsigned)
- 24-bit stack with overflow protection
- Programmable Priority Interrupts
- Oscillator Fail Detection
Key features of the first members of the Zilog ZNEO Z16F product family include:
- Up to 128 KB internal Flash program memory with 16-bit access and in-circuit programming capability
- Up to 4 KB internal RAM with 16-bit access
- 12-channel 10-bit A/D with 2µSec Conversion Time
- Internal Operational Amplifier, Analog Comparator
- Dual on-chip oscillator for 5.53 MHz operation or low power 32KHz secondary oscillator
- 4-channel DMA
- Two full-duplex 9-bit UARTS with support for LIN and IrDA
- I2C master-slave controller
- Enhanced Serial Peripheral Interface (ESPI) controller
- Pin compatible to ZiLOG Encore Series
