For engineers reviewing the MC9S08PA8VLC datasheet, MC9S08PA8VLC pinout, MC9S08PA8VLC application, or MC9S08PA8VLC equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options - all grounded in the official MC9S08PA16 Series Data Sheet Rev. 4 (03/2020) which explicitly covers MC9S08PA8(A) devices including MC9S08PA8VLC.

Technical Context

The MC9S08PA8VLC implements the HCS08 CPU core with up to four-level nested interrupt support and 40 interrupt/reset sources. Its clock system combines a 31.25 kHz–20 MHz external crystal oscillator (XOSC) and an internal clock source (ICS) with frequency-locked-loop (FLL), enabling precise 1% internal reference accuracy from 0 °C to 70 °C and 2% across full operating range.

Peripherals include two flex timer modules (FTM0: 2-channel; FTM2: 6-channel), a 12-channel 12-bit ADC with 2.5 µs conversion time and stop-mode operation, one analog comparator with independent rising/falling edge interrupts, and dual SCI modules supporting LIN protocol extensions - all accessible via 28 GPIOs in its 32-pin LQFP package.

FAQ

What is the maximum operating frequency and voltage range for MC9S08PA8VLC?

The MC9S08PA8VLC operates at up to 20 MHz bus frequency across a supply voltage range of 2.7 V to 5.5 V, fully specified over the industrial temperature range of -40 °C to 105 °C. This rating is confirmed in Table 1 (Ordering Information) and Section 6.1.1 (DC Characteristics) of the MC9S08PA16 Series Data Sheet Rev. 4, which explicitly covers MC9S08PA8(A) devices including MC9S08PA8VLC.

Does MC9S08PA8VLC support LIN communication?

Yes, MC9S08PA8VLC supports LIN communication through both SCI0 and SCI1 modules, each featuring optional 13-bit break detection and non-return-to-zero (NRZ) framing required by LIN 2.x specifications. This capability is documented in Section "Peripherals → SCI" of the MC9S08PA16 Series Data Sheet Rev. 4, applicable to all MC9S08PA8(A) variants including MC9S08PA8VLC.

How much flash memory does MC9S08PA8VLC have, and is it field-programmable?

MC9S08PA8VLC contains 8,192 bytes (8 KB) of on-chip flash memory that supports full read, program, and erase operations across its entire operating voltage (2.7–5.5 V) and temperature (-40 °C to 105 °C) range. Flash endurance is rated for 100,000 erase/write cycles, and erase occurs in 512-byte sectors - details confirmed in Section "Key features → On-chip memory" and Table 1 of the MC9S08PA16 Series Data Sheet Rev. 4.

What package type and pin count does MC9S08PA8VLC use?

MC9S08PA8VLC uses a 32-pin LQFP (Low-Profile Quad Flat Package) with 0.8 mm lead pitch. This package variant is explicitly listed in Table 1 ("Ordering information") of the MC9S08PA16 Series Data Sheet Rev. 4 under the MC9S08PA8(A) column for part number suffix "VLC", and shares identical pinout and signal multiplexing with other 32-pin PA-series devices.
