Description
The 83C154VF49 is an 8-bit microcontroller under the IC Chips category. It is a higher performance version of the existing MSM80C154/MSM83C154, providing low-power consumption. The MSM80C154S/MSM83C154S covers the functions and operating range of the existing MSM80C154/83C154/80C51F/80C31F. The MSM80C154S is identical to the MSM83C154S except it does not contain the internal program memory (ROM).
Specifications and features
- Operating range:
- Operating frequency: 0 to 3 MHz (Vcc=2.2 to 6.0 V), 0 to 12 MHz (Vcc =3.0 to 6.0 V), 0 to 24 MHz (Vcc =4.5 to 6.0 V)
- Operating voltage: 2.2 to 6.0 V
- Operating temperature: –40 to +85°C (Operation at +125°C conforms to the other specification.)
- Fully static circuit
- Upward compatible with the MSM80C51F/80C31F
- On-chip program memory: 16K words x 8 bits ROM (MSM83C154S only)
- On-chip data memory : 256 words x 8 bits RAM
- External program memory address space: 64K bytes ROM (Max)
- External data memory address space: 64K bytes RAM
- I/O ports: 4 ports x 8 bits (Port 1, 2, 3, impedance programmable): 32
- 16-bit timer/counters: 3
- Multifunctional serial port: I/O Expansion mode, UART mode (featuring error detection)
- 6-source 2-priority level Interrupt and multi-level Interrupt available by programming IP and IE registers
- Memory-mapped special function registers
- Bit addressable data memory and SFRs
- Minimum instruction cycle: 500 ns @ 24 MHz operation
- Standby functions: Power-down mode (oscillator stop), activated by software or hardware; providing ports with floating or active status. The software power-down stet mode is terminated by interrupt signal enabling execution from the interrupted address.
Application Scenarios
The 83C154VF49 is suitable for various electronic applications where efficient and low-power performance is required in operating conditions ranging from -40°C to 85°C.
Comparison
Advantages- Efficient and low-power performance
- Higher performance version of the existing MSM80C154/MSM83C154
- Upward compatible with the MSM80C51F/80C31F
- Standby mode (Power-down mode - oscillator stop) activates by software or hardware, providing ports with floating or active status.
Disadvantages- The MSM80C154S is identical to the MSM83C154S except it does not contain the internal program memory (ROM).
